HUGE THANKS to new Patreon supporters - Marcelo Soffiantini, Barry Arnold, Ron Studebaker, Daniel and Rose Evander, Dave Tyler, Mark Nesseth, Hill Robertson, Tili, and William Youngman. You are the ones making this work possible!
This video contains a great deal of technical detail and should help you understand everything you need to start taking pictures at extreme magnifications. I have deliberately not included sample images in this video. This is to allow the viewer to focus on the technical details without distraction. A followup video, demonstrating this setup in use, with many example images, will be forthcoming (Going Deep - part II).
Stuff you will need for 5X+ macro photography, as described in detail in the video. This list may work for for other, similar objectives - provided they are infinity correct with planar correction and built in achromat or apochromat chromatic aberration corrections. It WILL work with the Nikon CFI Plan achromat 10X/0.25, M25 infinity corrected objective used in the video. www.atlantamicroscope.com/Nik...
Both setups also require the use of a Raynox diopter (4.8) - DCR-150 (www.amazon.com/Raynox-DCR-150...) and either a set of bellows or enough extension tube length to reach the focal length of the Raynox (208mm) minus the flange/focal distance of your camera body.
Parts needed to mount Raynox in normal orientation:
▪ camera body
▪ extension tubes or bellows to fit your camera mount
▪ M42 to your camera mount, reversing ring - this example is for Nikon F-mount (www.bhphotovideo.com/c/produc...)
▪ M42 to M43 step up ring (www.amazon.com/Fotga-Black-42...)
▪ Raynox DCR-150 (link above)
▪ M52 to M49 step down ring (www.ebay.com/itm/Bower-49mm-5...)
▪ M25 to M52 objective adapter (www.ebay.com/p/620752119?iid=...)
▪ Nikon CFI Plan 10X achromat infinity objective (link above)
Parts needed to mount the Raynox reversed (my preference):
▪ Camera body
▪ Extension tubes or bellows to match your camera mount
▪ 52mm reversing ring (in your camera’s mount) (www.ebay.com/itm/52mm-Macro-L...)
▪ 49mm to 52mm step up ring (www.ebay.com/itm/49mm-to-52mm...)
▪ Raynox DCR-150 (reversed)
▪ 52mm to 43mm step down ring (www.ebay.com/i/151831400966?c...)
▪ 55mm to 52mm step down ring (www.ebay.com/itm/55mm-52mm-55...)
▪ M25 to M52 objective adapter (www.ebay.com/p/620752119?iid=...)
▪ Nikon CFI Plan 10X achromat infinity objective (link above)
Be aware that many of these adapters will be coming from China and may take months to arrive. Virtually all of them can be bought from sellers such as Thorlabs (thorlabs.com) and Edmunds Optics (edmundoptics.com), but expect to pay about ten times the price.
What can I say, this was the video I've been searching for when it comes to understanding objectives.
Thanks so much for the very detailed descriptive video.
I find your videos more and more interesting about extreme photography. Five years ago,I built an automatic focus staking rail for macro photography using a 105mm Nikon lense. From what I have learned with your videos I am preparing to go for extreme macro. Thanks for your help. Bye from Canada.
28:00 "they have em in strange sizes but they also have them in strange prices" LMAO!
Thank you Allan. Great watch!
Just watched this again to refresh my memory, enjoyed it just as much! Thanks.
Thank you so much for this informative video, I can listen to you for days...in fact I do watching one after another..so much patience and your voice is so relaxing 😀.
Please keep do what you do
Thank you ever so much for sharing all this precious knowledge in such a comprehensive and explanatory way!!!
God bless your work. I really appreciate your narration, patience and ofcourse your passion for macro.
Love what you do and how you do it! Appreciate the quality content! I'm a big fan of macroI Subscribed! Thank you for sharing all the info!
Thank you so much for sharing all your knowledge and showing us the way how to do (extreme) macro photography. I am not into extreme macro photography yet but it certainly won’t take long! I am so glad that I have found your channel so, steady on, I will collect the parts that are needed for this gorgeous way of photography. Thanks!
Great explanation Allan. Thanks!
Allen, I discovered this very same method. I also discovered that Nikon made a 200mm prime lens some years ago, and they are perfect for this and not many people want them because they dont have any Auto functtons. I got mine for $50
Just learned so much. Very educated and informative.
extremly helpful step by step instruction !!! well done , thanks
Thank you SO much for taking the time to explain exactly how things work. I LOVE your videos and am so grateful to have found you. A lot of people who make videos talk so darn fast and skip over so much that I walk away scratching my head only having part of the info I actually needed. You are amazing!
I just found this! Only six months late, but thank you!
Thanks Allan
Hi Allan, I just subscribed to your channel after watching one previous video. All the information you provide as well as the pace you deliver it and at which you speak, are great. Thanks for sharing and keep up the great work. Marco.
Thanks Marco - I'm glad you are finding it useful!

Thanks Allan another great video with a plethora of useful information!!!
Cheers, William - there was a lot of stuff in this one!
Thanks Allen, I agree with the others, excellent guide! I'm not a macro photographer, but discussion on these topics really help deepen my understanding of optics in general!
Thanks, Tristan... don't you mean you're not a macro photographer... yet. Hahaha... thanks for watching!
Thank you for making this video, Thank you very much
Thanks for the great video, look forward to the next one.
Already working on it!

Amazing work!
Viewed, learned and liked. Gave me a lot to think about...! Thanks.
Thanks for watching - more on the way!
Excellent video as always Allan. A somewhat tricky subject to cover but I couldn't have asked for a more layman-friendly introduction to it all. Keep up the good work!
Thanks Steven - I agree! The hardest part of this job is deciding what it is OK to leave out!
Great content!
Hi Alan, thanks for the great video. Question about the 200mm lens- is it possible to use a regular fixed 200mm/2.8 instead of the more expensive zoom lens? Will using a crop sensor (d80) change the setup ? (I believe not but just making sure) - and finally, what would happen when using a 300mm zoom? Thanks!
Very informative content. Thank you 👍
You are very welcome! It was great fun to make!
Thanks a lot.
Awesome Awesomeness. Love your Videos. I am a professional photographer and I learn so much from you.
Thank you Josef - that is high praise indeed - I have seen your excellent work.
Great content Mr.Allan Walls - Do you know any cheaper alternatives for nikon plan objectives?
Allen，is there a problem to use a finite object in front of the formal camera lens creating image on my sensor？
Hi Allan Did you purchase your copy of microscope objective from the link you provided at Atlanta microscope?
Well........I ordered a set of stepup and stepdown rings as suggested on one of your other videos. Also a 55mm reverse ring adapter for my Nikon d5600. My other lens needs a 58mm reverse adapter but I couldn't find one after my treasure hunt. You said that the stepup/stepdown rings would come in handy. Very good advice. //////For different background colors...I'm going to experiment...by using my computer monitor...it fits real nice but I may get some reflection. Just an idea.
Hi from Scotland under lockdown, I have enjoyed your Macro videos so much I've decided to get a macro lens and get involved in this exciting hobby. I noted in one of your videos you had a Scottish flag ( white cross on Blue background) so I checked your website thinking you were local ( I won't hold it against you being states side) keep up the great work.
Hello Phil, I was born and raised in the UK, but my mum and dad were Glaswegians to the core. I picked up the Saltire at a Calcutta Cup match a few years back. Almost all my remaining family are in and around Edinburgh. So I'm as close to Scottish as you are likely to find in Alabama!
Great amazing explane
Allan, when shooting stack photos, what are you using. Auto white balance or custom?
Excellent video Allen. Which bellows for a Nikon DSLR do you like?
Hi Allan, Ask how many megapixels camera are necessary when using 5x, 10x, 20x or maybe 50x microscope objective. How can I find out. Greetings Patrick
Thanks Allan, we learned a lot watching this. I'll have to go through my old ring adapters to see what I have. Do you know the t-mount interior thread size? Curious since it may make this simpler. Anyway, as we were watching I found a bellows for my Sony A7 at Walmart online (it was out of stock everywhere else) for $40 which seems like a good investment to help make my lenses more flexible. Looking forward to seeing you use the setup. I know you don't use a mirrorless camera. Do you think focusing might be easier?
Hi Dan. The T-mount thread size is identical to the M42 (42mm and 0.75mm pitch). $40 bellows! That sounds like a steal. I think mirrorless systems might make it easier to check focus at your start and end points, especially at higher magnifications. I may rent a good mirrorless like the a9, to see how it does - I know a lot of very good macro photographers who swear by it.
Hi there, your tutorials are awesome! thank you for doing that, i have a question. WITh GH6 it will work this setup? im using a speedbooster .71 and i have Canon 70-200 2.8 lenses. Im a videographer mainly and im knew to macro but i always love it .THANK YOU in advance, any other suggestions Wanted.
But how do you focus the bellows setup? Is the bellows adjustment fine enough to use for fine focus? Or is moving the entire construction the best way
Thank you Allan for producing these videos, really enjoyed watching this one, can't wait to see the images you produce from this setup,
Thank you for rekindling my interest in macro photography,
I do have a microscope objective 4x, markings on it say...
SP 4/0.10
160/0.17
would this be any good for close up photography? or is it one for the bin?
Hi James. That objective is a finite 4X with a pretty tight numerical aperture (0.1). It should work with the same 160mm (minus flange focal distance of your camera) of extension. You can ignore the 0.17 cover slip correction. I never throw out an objective without giving it a good trial. The setup for that objective is very simple (just an RMS adapter and some extension tubes), so give it a try - it may turn out to be superb!
@@AllanWallsPhotography Thanks for the reply Allan, will give it a try and see what it can do,
Hi Allan, let me know how you get diferent magnifications with Nikon 10X monting in a 70-200mm. thanks
Can you elaborate on how to use the Nikon 10x objective for magnifications less than 10X.
Hi, great video as usual. You mention being able to use 5x, 7x, and 10x magnification when on the 200mm lens, but did not mention how to do that. Is that possible with bellows too? Can you please explain? Thanks.
5X with the Raynolx 250, but 7x I don't know, dId you learn it already?
Sorry if silly question and new to these products etc, but looking up the objectives mentioned I came across a "bargain" on a 2k usd lens and wonder if it can be used as well. Mitutoyo M Plan Apo NIR 10x LWD Objective at 400 usd used, while the 900 usd one mentioned here was 650 usd used. Or is that something altogether different and not for the normal macro we do with it's infra-red thing?
Big thanks for sharing all that knowledge and for being an inspiration you are. I just purchased Canon 100mm Macro 2.8 to give a try to macro photography inspired by yourself. So far I can say that it is even more complex subject I initially thought but from the other side.. so rewarding. Of course +1sub from me. I cant imagine why youtube algorithm doesnt promote videos and people like you just all that noisy crap instead made by ppl who doesnt know much about the subject they try to talk about. You are such natural and easy to follow teacher. Please dont stop being amazing and take care. The youtube is definitely much better place with content creators like yourself. Keep recording and stay safe
Thanks so much for the encouraging words! I don't understand the algorithm either, but I don't plan on going anywhere!
Thanks Allan, impressive! so can i use 3 extension tube sets plus a 14mm to get to 161mm plus a 1mm (unsure if you can purchase a spacer/ ring) 1 x achromat 10X/0.25, 1 x M25 to M52 objective adapter. 1 x Raynox diopter (4.8) or do i need to take into account the width of the Raynox diopter (4.8)? thinking of ways i can get started on the cheep, the bellows are a price at present, ty Col
I ended up buying bellows
I'm a professor; And you taught me like a professor!
I am a retired professor - so that probably explains it!
Allan, great video as usual. I was amazed when I saw the function of disconnecting the end plate and reversing the lens. It appears I can also do that with my Pentax bellows. I must confess I have had a few bellows units in my time (Canon, Nikon, Pentax and Novoflex) and for the most part I think all high quality ones are similar. I don't think my PB-4 was really any better than my Canon or my Pentax bellows (I never mastered the shift function or was it tilt?). All I know is the PB6 has a longer rail. Anyway my PB4 was better than the old Novoflex but with that I could also focus to infinity. You said that the Chinese ones are (paper) junk (and I certainly agree). However they are cheap so there is not a lot to lose when trying this. The creator of Zerene Stacker once said in an article the best way to shoot a stacked image is to let the camera remain in its position and move the lens. Naturally you can do this with a bellows if you want to do it manually. But it does not work on a focus rail. Here is where the cheap bellows comes in, you disconnect it and mount the end plate to the end of your automated rail. I did it with my StackShot and it worked I didn't notice any real difference but I'm sure there is some. I'm just not good enough to notice it. I do believe he as well as you know more about this than I do. But if you have an automated rail it is a fun project.
I would like to suggest that if you ever get to use a connected reverse adapter go for it. I think they are only made for Canon (Novoflex calls theirs EOS Retro Adapter - very expensive like all Novoflex products) and their is a company called Mieke that makes one as well (dirt cheap and very good if not better quality - I have both). You have gone over reverse lenses, but this adds a new twist, no stopping down while focusing. Plus you can use it with a bellows with your normal lens and have communication . All this being said and after trying it with numerous lenses (none are as good as the 50 mm Nikon 2.8 N) you can get some incredible results. A 28-90 ends up being a 3:1 - 1:12 so a real macro zoom. You also mentioned Thomas Shannon in one (or more) of your videos, and in the field he seems to always use a revers lens. Anyway, if you get a chance please give it a go.
How do I find the "diopter value" so that I can determine the focal length?
I found a set of diopters from "Big Mike's" that are fairly thin and come in "+1, +2, +4, and +10". Is that the diopter value?
(for some reason, I don't see it listed on any of the Raynox listings.)
Are those Big Mike's diopters okay to use for this purpose or is is better to use the Raynox?
Very informative as always! You mentioned you already did a video on the 4X, but I can't seem to find it? I always look forward to your upcoming videos.
I think this is what you are looking for. th-cam.com/video/ZUIYW77HKZg/w-d-xo.html
No, I saw that one but thank you. I thought there was going to be video dedicated to the 4x just like this one was dedicated to the 10x.
Hi Mike... There are several recent videos where the 4X is used, but the this is the one where I talk about the finite 4X objective specifically... th-cam.com/video/ZUIYW77HKZg/w-d-xo.html
Than you Alan. I saw that video & was thinking there would be a follow up video due to what I read in the show notes. You mentioned getting specific gear to follow along with you, such as a focusing helicoid. Thanks for the very informative videos!
Patronized ;) Awesome
interesting video well explained. It would have been good to show some sample photo's of the effect of depth of field. also perhaps a Barlow lens from a telescope eyepiece
In 25:20, why does it need to be 200 mm lens? Can I use the objective lens with a 100 mm macro lens (Canon)?
nice video, by the way "planner" is a trademark name, same as T* is; these are from the Hasselblad lenses, ie: Carl Zeiss lenses manufactured for their V and H medium format camera platforms. that is why the name had to be modified, as these names were around since 1960's ( as they were used on Hasselblad cameras in space).
Hui Allen, would love to see a video on 20x or 30x and how pheasible it is at home? Cheers
I have an old minolta 200mm F4 telephoto - would that work as a tube lens?
Another great video Allan - I must have missed this one. I currently use Helicon Remote to control my Canon 100mm L macro lens for focus stacking. I also use it with a Raynox 250. Do you think I could focus stack using Helicon Remote with a microscope objective on a 70-300mm telephoto lens and have the focus controlled by Helicon Remote? Currently, my setup works well outdoors and a small tablet controls the camera and taking focus slices from front to back of the subject. Thanks again for your clear and concise teachings!
Hi David, Helicon Remote is a valuable tool for use with a macro lens but it won't work with a microscope objective. Helicon Remote is a tethering program that uses focus bracketing to adjust your focus using the lens' focus mechanism. In order to stack with a microscope objective, even when using a 200mm telephoto lens as your relay device, you need a way to physically move your fixed 200mm relay and the objective, and the camera, as a unit. The relay lens must be focused at infinity for an infinity corrected objective form an image on the sensor - and changing the focus of the relay lens using Helicon will not focus the objective. If you have a Stackshot or a WeMacro rail, you CAN control that with the Helicon software, and focus stacking with an objective becomes straightforward. Hope that helps!
@@AllanWallsPhotography Thanks Allan! I thought it wasn't going to work using the lens focus mechanism. Time to think about going back to a rail for extreme macro. Much appreciate your time to respond!
Hello, what happens if i dont have a 200mm lens to use behind the Nikon Objective? Will a 135mm nikon work? What will the outcome be if this is used instead of a 200mm lens. Do I need to use my 2x teleconverter behind my 135mm lens?
Thank you Allan. I am hooked. But I cannot find 200mm extension tubes for Sony e mount. Frustrating, but I will persevere!
B&H has dirt cheap $9 sets (get 3 sets) for Sony E. But failing that Fotodiox makes those tubes and you can get them from their website. Or get a cheap adapter (Sony E to Nikon F) and use Nikon tubes which are always available. Or buy a length of PVC tube, flock it, and epoxy a body cap to one end and a lens cap to the other - hey presto - extension tubes!
Allen, I have bought this lens and it really is a game changer. The Nikon 200mm prime is perfect. I am having trouble finding an adapter for the microscope lens. I am mounting the lens to the front of the Nikon. I have tried 25mm thread adapter, and the pitch of the thread is not quite right. I can thread the objetive about one revolution and no more. Is there a complete definition of the thread? Or better yet, a known good adapter? Thanks.
Is it better to have a longer focal length if using another lens to bring the light in from infinity?
thanks for the informative series. I have a question about 4x finite objective. can we use different than 160mm distance? or it must be exactly 160mm focal lenght. i plan to use with bellow . for lover magnafication can i reduce the distance? is it effect image circle?
Good question... You could theoretically change the magnification of a finite system by adjusting the tube length, but it result in degradation of image quality with every mm over or under the tube length the objective was designed for. This is because the finite objective is constructed to optimize aberration correction at its tube length. The limiting factor is spherical aberration, which is minimized at the tube length designated on the objective.
Allan, thank you for your explanation for everything, I learn lots of it. And I start to build a system of myself. About these, I am confused one thing, that you mention that about the distance about objective lens and Raynox - DCR-150.
For example, you mention in this video that Nikon plan 10x 0.25 WD10.5 objective lens need as close as you can with the Raynox - DCR-150.
But in another video(When Mitutoyo Met Raynox - How to set up a Mitutoyo 5X objective with a Raynox tube lens (+more)), you said that Mitutoyo 5x objective lens best need 30mm distance between the Raynox - DCR-150.
So which one is correct or better?
Or it all depend on the different objective when we use?
Theoretically, it should make no difference, provided the infinity space is not so large that vignetting occurs. The distances that I recommend are based on my own experience. There is really no science behind it. Some objectives perform better very close to the relay lens, others are prone to reflections when close. I urge you to experiment and use the distance that works best for you.
I scrolled through your video and may have missed it but did you show anything that you looked at through the lens? In other words did you show something that you magnified?
Hello Antonio - no, I didn't. As I explained at the beginning of the video, there was so much material to cover I decided to split the video into two parts. Part one was all about building the proper setup and making your own relay tube lens. Part two will cover using the various lens combinations, and will have a ton of photographs taken through each system. Part two will be released this coming week.
Hi Allan,
I love your work, and watching you has inspired me to explore some extreme macro myself. I recently picked up two sets of vintage Asahi Bellows at a thrift store but now I'm having difficulty figuring out how to mount my Sony A7Rii to the M42 mounts.... or rather, I'm having difficulty figuring out how to mount my Sony E-mount lenses. I've only found adapters for Nikon lenses to M42 bodies and cannot source a Sony lens to Nikon body adapter as they only seem to be available the other way around, likely due to the popularity and age of the Nikon lenses vs the Sony E-mount range. do you know of any workarounds for this or are my bellows useless until I purchase a suitable non-sony lens?
Regards, Milson.
Hi Milson - Have you looked at this... www.adorama.com/mtkltm2m43se.html?gclid=CjwKCAiAsOmABhAwEiwAEBR0Zqdp_5tTduCJzvNg3awrv7ZytXzLyH9KCTgcAmoqF9a3Q83rcsXbtxoCeYUQAvD_BwE&gclid=CjwKCAiAsOmABhAwEiwAEBR0Zqdp_5tTduCJzvNg3awrv7ZytXzLyH9KCTgcAmoqF9a3Q83rcsXbtxoCeYUQAvD_BwE&
This will mount on your Sony and allow you to screw the bellows onto the adapter. At the other end you will need an M42 to Sony lens mount adapter, but they don't actually exist. This is because of the much longer flange focus distance on an SLR/DSLR. You can't mount mirrorless lenses on DSLR bodies because the mirror gets in the way (you can't shorten the FF distance). Therefore, nobody makes the kind of adapter you need (even though it would work fine with bellows). Here is what I would do... use the Sony lens in reverse. Then you only need a couple of step up rings to get you from M42 to your lens filter thread. In fact, you can mount any lenses you own, in reverse, with just a couple of $5 step rings. Hope that helps!
@@AllanWallsPhotography Thank Allan. Yeah that was the alternate Workaround I was looking at too. It's a pity, I was really looking forward to playing with my Laowa 100mm 2x on the bellows, but I guess i can always reverse it too.
thanks again for your knowledge!
@@milsonbarnard8464 I think you would be disappointed using a macro lens on the bellows. They really shine using reversed, short focal length primes - 35-50mm. Macro lenses don't offer much when reversed. You really should try a couple of dirt cheap enlarger lenses - best bang for the bellows-buck.
Excellent information. I have a thought. I have an old Takumar M42 150mm lens and can mount the Nikon to the front. That would give me less than 10X. What about using it setup like that then just put extension tubes on the back of the Takumar and increase magnification that way. Would that cause problems or would that actually work? I do have a AmScope 10x Plan but seems soft even at 160mm but it is designed for 160mm. Might be light placement but just a thought. For now I'll stick with my 4X and work on my lighting.
Hi Pete. Interesting questions. You certainly can use the Takumar 150mm as a relay lens, but you can't add any extension. The tube lens (the Takumar) needs to be used focused at infinity, (and wide open) which you can't do if you add extension. I would use it at its focal distance and try to find an M25 to M42 adapter that will place the objective as close as possible to the front of the relay lens. You may end up having to use an M25 to 52mm adapter and an M52 to M42 step down ring. I know the AmScope 10X of which you speak - but that is a finite objective. It is rated for an RMS standard 160mm tube length, but will be a lot sharper at 150mm from the sensor (which is the optical tube length). By the way, the first setup should get you to around 7X.
Oh Allen..... What can I say... You have perfected the cure for INSOMNIA !!!! 😴😴😴😴😴
Hello Allan! Thanks very much for your videos. a question about notation: is an M42-M43 step up ring adaptor equal to a 42mm-43mm step up ring adaptor? I mean, is the "M" notation the same as a "mm" notation? M42=42mm? Thank you!
I too want to know this
@@mynameisben123 I learned it is equal!
So am I correct in thinking if you mount the 10x on a 200mm lens you get 10x magnification, on a 100mm lens 5x, on a 50mm 2.5x, also if you go down the lens route will the sharpness of the lens be reflected in the overall sharpness?
Hi Alan, thanks for your very clear explanations. You mention that macro lenses in this kind of configuration are not really the best ones, however, i can see that Levon Biss use a Nikkor coupled with what seems to be a 10x Zeiss Microscope lens on a D810 Body in order to achieve really impressive final images. What are your thoughts about his particular setup? Thanks in advance.
Excellent question - Levon Biss uses a 10X infinity corrected objective mounted on a 200mm prime telephoto lens. The choice of relay lens is not critical, you can get fantastic results from a 200mm tube lens, a 208mm Raynox diopter, or any 200mm prime telephoto lens. Using a prime works a little better than some 70-200mm zooms, but there isn't much in it. But a macro lens, even if it is a 200mm lens, does not work well as a relay lens. This is because the entrance pupil of the macro lens is, by design, deeply recessed, allowing the lens to focus at short distances. I have experimented with the Micro Nikkor 200mm f/2.8 (a true macro lens) as a relay lens, and the results have been very disappointing. If you have different information about Levon's setup, I would be very interested in knowing - because, if anyone has figured out how to overcome the problems of using a macro lens as a tube lens, it would probably be Levon!
@@AllanWallsPhotography Thanks Alan for your message, i was researching more about Levon's setup and found out that he update it with a dedicated tube lens and vertical position for the amber specimens
@@DominicanAmberFossils That doesn't surprise me - a dedicated tube lens, mounted inside the extension tube assembly, is a very stable, less bulky, and optically ideal choice for a relay lens. Thanks for sharing the updated setup!
Allan, I will try the 10X on my Nikkor 80-200 2.8 D series lens. Should the lens be set at its widest aperture? Hope you're doing well.
Hi greg - yes. Use the lens at 200mm, wide open and focused to infinity. The objective will do the rest!
Hi Sir, Thank you for your Genius teaching, dedication of your time and sharing your knowledge with us. I have a doubt between finite and infinte microscope objective lenses.
You have clearly explained the difference between finite and infinity.
But what is going to be the specific and exact difference is going be on our photograph while using a Nikon E Plan 10x/0.25 infinity WD 7.0 vs Nikon E Plan 10/0.25 160/-
The WD is not mentioned in 2nd lens which i mentioned and also 'x' is missing before the numerical aperture value. Does this have any significant mentions?
Thank you!
Hi, it is not unusual for older finite objectives to omit the working distance from the barrel markings. I can tell you that the WD with this objective is quite restrictive. I haven't used one in a long time, but I seem to remember it having quite a lot of color fringing. If you are trying to choose between the two, I suspect you will be happier with the CFI E-Plan infinity corrected objective. Good luck!
@@AllanWallsPhotography Thank you very much for your reply sir. I will buy the CFI e plan infinity corrected one 😊
I feel bad. Left you to learn a little bit about portrait photography and got captured by the pretty models. But I'm back. I finally got my Nikon d5600 ordered and it's being shipped as we speak. My bank kept locking by debit card and never told me. It's a security thing when purchasing expensive toys from another state (New York). Its going to take me a couple of months to get started in macro, but will eventually get there. Great video. Now I just need to make my wish list. It's sort of fun trying to locate all the parts.
Hi David - you are so right! I spend far too much time digging around to find obscure adapters to try out crazy new ideas. When it comes to being fixated on gear, we macro folks take the cake. I'm excited you have the D5600 on the way! Good for you!
awesome video as always.heres a question i doubt anyone will answer but here it is.according to novoflexs site,the mft mount bellows im lookin at gives a 5.7:1 magnification with the 60mm olympus macro lens.is it better to get that instead of the laowa 5x 25mm lens,since the bellows will be handy in the future for greater magnifications?i think it is but im not sure yet.also,if i decide to go 10x with the nikon obj,i guess im gonna need the bellows anyway?...so...anyones opinion is welcome at this point....
i guess the laowa would be good for field use to avoid damage on the bellows? im still trying to get as much as possible out of the available options on a finite(and rather limited) budget...so basicaly im thinking of the novoflex bellows(i dont wanna get something used cause u never know what use and abuse it had)+ the miops slider...
Mr. Alan, I've bought the Nikon CFI Plan achromat 10X/0.25, M25 infinity and already had the Raynox diopter (4.8) - DCR-150. I'm looking for advice for the best lens for a full-frame Sony A7iii camera, possibly (Sony FE 70-200mm F4 G OSS). I bought a 90mm macro lens a year ago and would like to take this to the next level, as you stated. Thank you in advance...
Hi Jamie, you already have two sweet setups for macro, a standard length macro (the Sony 90mm or 3rd party?) and a great 10X objective. What you don't have is anything to fill the gap between the macro lens and the 10X. If I had the money it would be the Mitutoyo M-plan APO 5x every time - best macro lens in the world - hands down. If you don't have the $$, get an Amscope 4X finite objective, or an El Nikkor 50mm f/2.8N enlarger lens and a set of bellows. If you are a billionaire, get a Nikon D850 and buy two Micro Nikkor 200mm f/4 ED-IF AF lenses and send one of them to me. That is the sharpest macro lens ever made.
Well Allan, after watching your video's I have now ordered everything I think I'll need. So I just hope that the Chinese don't fall out with us in the meantime. The Objective was hard to find but eventually found a UK site, Ultramacro.co.uk who specialise in macro photography with objectives, stacking rails/software and many other accessories. So hope this a help to other fans of your photography from the UK.
You talk about some of the literature about this subject. Can you advise where I can go to find this myself?
Hi Art, A great source for understanding Nikon's optics is www.microscopyu.com. Mitutoyo and Olympus both have great resources on their microscopy sites. For a deep dive into the practical side of tube lens use in photography, I would recommend www.closeuphotography.com. If there is some specific area of photomicrography you want to read up on, let me know (contact@allanwallsphotography.com) and I will point you in the right direction.
Hi Allan,please which extension tubes are best to buy. Thanks in advance.
Hi Mario! Good to hear from you! I use the cheapest 52mm tubes I can find. www.adorama.com/fdmacrotnikf.html?gclid=Cj0KCQjwhtT1BRCiARIsAGlY51IPKImD_Oly-sUSnlUO5CiLChZK1t4jl9s9-DxXKSJtmjiAAnPjLbMaAm4WEALw_wcB&
These don't have any electrical connection (which you don't need for most things) and they are made to fit most camera brands. I use these same tubes, with excellent results.
May I ask:
- His bellows are different from the ones on ebay
Why later
Thank you
Please help me buy the Nikon Bellows PB-6 just like yours
Allan, have you ever tried this with a Micro-Nikkor 200mm lens. I have one: it has a 52mm filter ring and with the FTZ adapter works well on my Z7. Any thoughts?
Hi Robert, I apologize for the lateness of this response, but yes I am familiar with the Micro Nikkor 200 mm lens. I presume you are talking about the f/4. It is one of the sharpest macro lenses on the planet. I no longer have the lens but I have several friends who do and one day I will add it back to my collection. I have not personally used this macro lens as a relay lens with a microscope objective but there are several very well-known macro photographers who use it as their go to tube lens. Levon Biss is probably the most famous of these. I have always avoided using macro lenses as tube lenses as I have found them almost universally disappointing, that is the reason I have never tried this particular combination. But when I get another 200 mm, one of the first things I plan to do is use as a relay with the Mitutoyo 5 and 10x objectives. You will need the FTZ adapter to mount the lens on the camera but this will place it at the correct length for the focal distance. I would go from the 52 mm filter thread stepwise using step down rings to 26 mm to mount the Mitutoyo or 25 mm to mount the CFI plan Nikon objective. This will give you approximately 25 mm of infinity space. Let me know how it goes, I will be most interested to hear your experience.
I suspect the M42 to F mount is easy to find because M42 was a common lens mount in the past (see all the Russian lenses from the Cold War era). It might be the wrong thread size though.
Any photo or video captured with this lens?
Respected Sir, Nikon plan 10x/0.25 is way out of my reach, please suggest me an alternative, my setup is D850 + Nikon 200mm f/4 Macro + Raynox DCR-250, I do not know how am going to manage the 25mm adapter for the alternative plan but I may use the Microscope Mount Adapter which comes with the T2 ring, please advise otherwise, I have never tried this & will be my first attempt at whatever I do, Thanks for inspiration all the time !!
Greetings! I hate to say it, but there is no competition in that price range. I have tried so many inexpensive 10X plan objectives, finite and infinity corrected, and the trade off in quality is really dramatic. The CFI Plan 10X Achromat is, for me, the perfect balance of affordability and quality. Most objectives that perform as well as the CFI are going to have price tags of $500 and up (way up) on the used market. Objectives like the Mitutoyo M Plan and BD Plan Apo (out of my price range, too). You can buy finite objectives from AmScope, in the 10X range, but the image quality is not worth the $30 investment. I would not recommend using the Micro Nikkor 200mm as a relay lens. The DCR-250, mounted at it's focal length of 125mm, makes an excellent tube lens for the CFI 10X plan, but will reduce the magnification to 5X. If you wanted to get into higher magnification (4-5X) on the cheap, I highly recommend the AmScope 4X finite objective which needs only extension tubes and an RMS to F-mount adapter - and gives awesome images for about $20. For $50, you may be able to find a Lomo 3.7/0.11, which is even sharper. But they are getting very hard to find. But if you are trying to get to 10X, you simply won't find a better infinity corrected objective at the $199 price of the Nikon CFI (IMHO). One other thing, even if you go with another 10X infinity objective, you are still going to have to invest in a 200mm tube lens, or a Raynox DCR-150 (focal length 208mm).
50:42 there are some that, in stead of an helicoid, have a screw to adjust the extenssion tubes length and are even cheapper, I'm sure you know that. Are they any good?
Hi João, yes indeed. That would work fine, as long as the screw section is well engineered. The cheap ones can cause sagging and result in alignment problems.
Thanks mr Allan, please i have raynox dcr 250 can I use it in this set up please?, and the distance between the raynox and the objective can i use the cone adapter m42-m26? Thank alot ❤️❤️❤️🌹🌹
Hi Mohamed - Great question! You can use the DCR-250, but you will need to use it with a tube lens of 125mm focal length. It would be exactly the same as the setup for the DCR-150, except for the extension distance (or bellows length). However, using this objective with a 125mm tube lens will only give you 5X magnification. The tube length should always match the focal length of the diopter you are using (125mm for the Raynox DCR-250 which has a diopter value of 8.0). Hope that helps!
@@AllanWallsPhotography Allan thank you so much for the video. i find it very helpful. one thing is on my mind. i understand from the video that i can use the nikon 10x for other magnification between 5 and 10. for example i want to use it for 6 magnification or 7 magnification. and i understand that both raynox that you mentioned wont give me the goal. cause of the focal lengh of the diopter. so how can i get the 6 magnifaction???
Great, informative video. Very helpful. I look forward to your videos. Many Thanks indeed!
Thanks - I'm glad you found it helpful!
Allen, Huge abundance of fantastic technical information here which will help us out here in the hinterlands-of-macro. It is worth mentioning that
all of the major "four" objective manufacturers produce (M20 ??) objectives for finite and infinite class. The RMS M25 thread is a very small percentage and are very expensive. So, the dominant objective source is RMS standard (Royal Microscopical Society) for mechanical compatibility
where the objective has mounting threads that are 20.32 mm in diameter with a thread pitch of 0.706.
Do you know how to adapt down to this 20.3mm "spec" with rings & tubes ?
Thanks for all your amazing work and knowledge in the macro arena !
Hi Gary, Most of the modern, higher NA objectives that we use in macro photography require a larger thread to accommodate the optics. Two common examples include Mitutoyo's 5X Plan Apo, which has an M26 mount and Nikon's Plan Achromat 10X which uses the M25 mount. And these lenses are expensive, to be sure. Many less expensive, short working distance, low NA objectives still use the smaller RMS (20.32mm) mount. So while there may be a broad range of RMS objectives available, they are not always the lenses we would choose to use as photographers. Adapters for every objective are pretty easy to find on eBay, where you can pick up an RMS to M42 adapter for about $6. In my experience, finding adapters for M25 and M26 objectives is not a problem. As I generally use M42 extension tubes, I keep adapters for all of the comments thread sizes on hand, and use them interchangeably, though I only have one RMS objective that I use regularly (the amazing and cheap AmScope 4X finite objective).
@@AllanWallsPhotography Thanks for the help and clarification. So, ultimately you are chasing after more light gathering power
when you use higher Field Number (FN) objectives. The Working Distance and NA specs of your Nikon 10x Plan Achro is very typical
of low cost 10x objectives. What you are paying for is the larger (Plano) FN which provides a slightly larger (projected) field-of-view for potentially more exciting final images. Side-note: The AmScope "Plan" objectives are VERY good, surprisingly. I have evaluated their 160mm 10x Plan, 20x Plan, and 60x Plan and I was amazed at the performance for such ultra LOW COST. I don't know anything about their "infinity" objectives. Some day, I would love to see you produce images with 4x (or 5x) infinity Plan objectives that are typical Field Number and 20.3mm mounting. As you know, it is much easier to push light in and around specimen and the depth-of-field is far better. Thanks again for ALL your great productions !
Just bought the Nikon 10x for 280.00 new. Best price I could find. No shipping or tax. I was looking on eBay but had a lot of concerns about what quality I would get.
That is more than I paid for new one, but I bought mine during the Ottoman Empire so I'm not surprised the price has gone up a bit. Still one of the best 10x lenses for the money. Congratulations!
@@AllanWallsPhotography The prices I saw varied new from 280.00 to 340.00 not including shipping and taxes. I didn't have to pay shipping or taxes so felt like I got a fair price. There's one on eBay for around 170.00 or so if anyone's interested.
Alan, I have watched a number of your videos and have certainly learned a lot regarding macro photography. However, I still consider myself a novice in this area of photography. Perhaps, my inexperience is why I have the following question.
In watching your videos on macro photography, I have seen an amazing array of various components all designed to produce macro photographs up to (and possibly beyond) a 10X magnification. Some of these components are fairly complicated to assemble and use - such as the use of your 10X microscope objective attached to a camera through a fairly complicated lens configuration. That leads me to the question (especially with this latter configuration):
Why is it necessary to go through all these gyrations with various lens/camera components to get a high magnification photograph of an insect? Why not scrap all the parts and accessories, buy a decent dissecting microscope (perhaps a stereo-dissecting microscope with 2 eyepieces), get an adapter to allow one's camera to attach to the microscope, and you are ready to go? This would provide a fairly quick setup of the equipment and a fairly quick take-down and storage of the various integrated parts. The microscope would also provide a "stage" on which to place the subject and allow lighting from underneath and/or from the top and sides (using separate light sources) with close to a 360 degree placement of the light(s) anywhere around (and too some extent) above the subject.
I have been wondering about this for awhile now. This video seemed like a good place to ask the question since the subject is about "Going Deep" with a 10x microscope objective.
