Thanks David. That's exactly why I am doing it. Such a small amount of sample footage or thread posts with mis-information. It was an area that needed some solid data and I figured I might as well do it.
Yeah definitely. It works with S35 sensors with approx 1.1-1.2x cropping to remove the very slight vignetting. It works great on both my FS7 (S16 and S35) and with my A6600 (S35). Would work just as well on a FX30 ☺️👌
Fascinating stuff. I've shot a music video with the ursa broadcast G2 and the canon hj22ex7.6b lens and the quality was amazing. The things you can do like hard zooms just blew my mind. Will definitely be ordering an adapter for the C70.
Excellent presentation, very thorough and to the point. What are the 35mm full frame equivalent focal lengths of the various potential kits in different formats? For AFL football 24-400mm+ is ideal. Will any of your kits offer that range? Exited :)
Hey Benny, thanks for your support. As far as the FF equivalent focal lengths to the kits, they should easily cover the long end of the range of 24-400mm equiv. The Canon J21x7.8 f1.8 shown in this video has an approx full frame equivalent focal range of 28-570mm. Then if you are in S16 and can use the doubler to gain extra zoom range it goes up to approx 1000mm worth of reach Another example the Canon J16x8 f1.8 I tested is a full frame equivalent of approx 28-448mm again doubler could be engaged for extra reach if you are capturing in S16 mod. In S35 mode in each case you just get the base range of the lenses as the doubler just provides sensor coverage rather than extra range. Thanks for the question :)
Great work with these videos. They're a great resource! Thanks for what you do! One question. I assume this lens support 6:25 is custom made? I've been looking for a solid solution that doesn't cost an arm and a leg, and this seems to fit the bill. Curious if you could shed some light. Thanks again!
Hey Devin, I am glad you are finding the videos useful 😊 I thought it was about time there was good recent info on it. Since nobody else seemed to be doing it, I thought I would do it myself. For the lens support, yes I custom make them to fit the specific lens. Definitely worth using as it secured the lens in 4 directions. Compared to a more typical support that just gives support from 1 direction (underneath).

Hi James just found your videos on TH-cam. Not sure you can help but here's my situation. I use a Panasonic GH5 to shoot surfing video in 4K. I have a Canon YJ19x8B 9-171mm ENG lens. It has a doubler built in and works great. But, I've noticed some small smudge like dots when I use the doubler. It looks clean without the doubler. I haven't been able to get rid of them with cleaning. So, I suspect it's on the inner elements. I also have a Canon YH18x6.7 ENG lens but there's no doubler and the ENG to MFT adapter dosen't fit it either.The Lens looks immaculate. Do you have an adapter that would make it useable on the GH5? Would the adapter have a 2x converter on it? I'd loose some telephoto range but it would work for me if I could adapt it. Thanks John Beattie
Hey John, It's probably mold or similar on the doubler element. Could be worth trying to disassemble and clean if you have some basic lens tech skills. I can't help you with the YH unfortunately, that is a 1/2" lens rather than 2/3" B4. The image circle is much smaller, flange depth is much shorter and the mounts look similar but are not compatible. I only play in the 2/3" B4 space as it's much easier to adapt. I do know RA adapters make/made a 1/2" adapter with a 2x element, but it is not corrected for a clean image. Best bet is it clean the YJ or replace with another clean 2/3" lens with doubler. Good luck 🤞☺️
@@jamesandcamera Thanks for the fast reply. I figured it is the lens of the doubler. I certainly would be willing to try and disassemble it. But not sure what the proceedure is. Do you know of a source where there might be instructions? I've googled but didn't find anything. Thanks

Hi, glad you found value in the series 😊 For B4-PL optical correcting adapters, the best option is the IBE 1.4x. it's very expensive though. The other option is by MTF at a lower cost but from what people have told me, less image quality. The 1.1-1.5x magnification ratio with correction is what suits S16 sensors/film size best. Be aware that all the B4-PL correcting adapters have parts that protrude deep into the mount, so check clearance of mirror box etc before mounting/running the camera to make sure it won't obstruct or damage the mirror/shutter.

Thank you so much for the incredibly informative video. I have a question. Would a Metabones speedbooster with a B4 to EF adapter ring function in a similar way? My Speedbooster is EF to MFT.
Hey, glad you enjoyed the video. Unfortunately not, speed boosters don't correct for an RGB focal offset. They also condense the optical path, which shrinks the projected image size. Whereas you need to expand the projected image from a 2/3" B4 lens as it is projecting too small for any common CMOS sensor camera. That's why the optical corrector, expands the image 1.1x (some do a higher expansion too) so that the small projection size is enlarged to fill a larger sensor. It also has special coatings on the optics which align the RGB wavelengths to correct the offset. Additionally I have tried using a metabones speed booster in my very early tests with the idea, and it actually makes the image worse 😬. Better image quality from just using a lenses built in doubler on its own for a small correction.
It works on the pocket 4k in later firmware versions with the S16 scan mode. It won't work with the 6k as it is not made for reflex mounts cameras like EF mount. Prices for each adapter depend on the design I make in that batch.

@@mynameis9389 No plans to make one for full frame. It is by far the most asked question I have got. Unfortunately people do not understand the physics of what they are asking. Expanding the image to cover FF requires approx 4x-4.5x image expansion. The main thing is you are taking a f1.8 lens, and reducing the light transmission so much that it will be the brightness of approx T10+ when the iris is set wide open. Making the lens harder to use at night or even just indoors without using a a high ISO degrading the captured image with noise. Expansion to S16 makes for T2.5 approx. and expansion to S35 makes for T5.6 approx. The best option is to use an old FS7/FS5 or if you absolutely must have a full frame camera, use an FX9 with FF, S35 and S16 scan modes.

I have a Canon EF S35 body I want to use a B4 lens on (Canon YH18x6.7 KRS SY14), do you make an optically corrected mount adapter for B4 2/3 to Canon EF?
Hi, no I don't make one for EF, it is much more complex compared to adapting with optical correction to a mirrorless mount. The only one I know of that can work with EF only works with the C300 MK2 in S16 centre scan mode, not S35.
I have an fs5 and an fs700, and I already have a BMD URSA mini B4 adapter, I just haven’t yet engineered a solution to add an E mount and spacer to the B4 adapter. How can I contact you to organise to purchase just your back half of the e to b4 adapter? Thx.
Yeah the FS5 is a great option for it having both S16 and S35 scan modes. Unfortunately I don't sell just the back converter part itself, and have put a pause on making the adapters till December to focus on a few other interesting projects and redesign the adapter. I definitely think it is worth having a go at making the part yourself if you already have the mount, as it is not too hard to get the fitment for basic functionality. The only hard part is strengthening the part once you have the functional fitment.
@@jamesandcamerawould you be able to tell me the size of adapter I need to make to match the e mount flange distance to the BMD ursa mini flange distance? I might try doing a 3d print, maybe I’ll use an m42 to e adapter I already have.
@@Philip-Dickinson-Studios sorry I can't tell you the flange depth. I agreed with a friend who worked with me on the R&D for it that we would keep it to ourselves. However I can say it is not too hard to find if you can use a short helicoid or just short adjustable tube spacer to test different depths. Otherwise you could always do some math based off the size of my adapter in the video footage and get pretty close on your first try.
Hi James...very interested in purchasing this adapter for my GH6. I can also help you with any testing you might need for the m43 version. I have several SD, HD and 4K Canon and Fujinon b4 lenses at my disposal including 50x and 70x Fuji box lenses we can test it on. Thanks Anthony
Thanks for your video, I have a Canon TV Zoom lens, J15x9.5B 9.5-143mm 1:1.8, I would like to mount this lens on my Panasonic GH5, Would this adapter work with this camera body and lens, and where can I purchase the adapter. Thanks for your help.
Hi Joaquin, thanks for your interest. I can make the adapter to fit the Micro4/3 mount. As far as coverage of the sensor goes, you will need to find out for yourself if the GH5 has a S16 size scan mode or is able to clear image zoom to an equivalent crop for it to work. The J15x9.5 is quite an old SD lens, I would recommend something newer for a better image quality. I have just tested a Fuji 7x7 from around the same time and it only really got decent image quality at f4 with a corrected adapter. Where newer SD lenses perform well from f2.8. As far as buying the adapters are currently out of stock and I will build a new batch for people to buy to be ready September 2024.
I've reached out to you over Instagram Messenger, but I'm not sure you'll get it. I have 3 Black Magic Pocket Cinema 4k's (MFT mounts) and would like to control zoom and focus from the tripod handles. I am simply streaming content from my church and we are currently using photographic lenses & Cine Prime lenses. We would prefer to be able to zoom a shot in without having to switch to a different shot and having to focus manually, etc. Is this something your adapter and kit can help me to do? We are not streaming in 4k - really more like 720p due to our streaming platform limitations. Would love to see if this is our ticket.
@@jaymnonlyjapanese we did. What info would you like to know? We ended up getting a Fujinon B4 lens and an optical corrective adapter that we are using on our Black Magic Pocket Cinema 4k camera. We also got a remote zoom command with an adapter. The focus demands are quite expensive and we haven’t gone there yet. We are hoping there might be an inexpensive solution soon as many of them are $1000 or so. However, in our situation, we don’t need to change focus much and since the lens is parfocal, it really does most of what we need without a focus demand.
Great Video!!!, Good info for us B4 ENG lens Users ,,,, I Have the B4 15x9 KRS , older version Lens and have an adapter for the Panasonic AF101 camera, works fine, But I'm interested in using the lens on my Sony PMW F3, Fotodiox sells the adapter , though I don't think it has the Glass inside the adapter , and the super 35 Sensor will probably cause major Vignetting in the shots.....I also would like to use the lens on the Sony FS7Mk2 ... Any information would be greatly appreciated , Thanks Alex...........
Hey Alex, first I would need to know the exact model code (eg: Canon J16x8B4-...) of the lens to make sure it is worth you going through all the trouble 👍 The optical correcting adapters I customise can work with 2/3" B4 lenses and convert them with corrections and a slight image expansion to Sony E mount and other mirrorless mounts. There are other manufacturers who make more expensive optical adapters too such as IBE, MTF, Abakus, Sony and Canon. I do NOT recommend Fotodiox for B4 adapters, from my experience I don't think they are optically correct and don't produce a clean enough image. The adapter I customise is optically corrected and cleans up the image so that is like using on a native B4 3CCD camera. It suits S16 sensor sizes and can cover 98% of a S35 sensor when using a lenses inbuilt doubler. It is perfectly suited to FS7/FS5/FX9 with their S16 center scan mode and S35 capture mode. Hope that helps 😊👌
I love it man. You’re the only one putting out content on these systems.

Hi, no I don't make one for EF, it is much more complex compared to adapting with optical correction to a mirrorless mount.
The only one I know of that can work with EF only works with the C300 MK2 in S16 centre scan mode, not S35.
I have an fs5 and an fs700, and I already have a BMD URSA mini B4 adapter, I just haven’t yet engineered a solution to add an E mount and spacer to the B4 adapter. How can I contact you to organise to purchase just your back half of the e to b4 adapter? Thx.
Yeah the FS5 is a great option for it having both S16 and S35 scan modes.
Unfortunately I don't sell just the back converter part itself, and have put a pause on making the adapters till December to focus on a few other interesting projects and redesign the adapter.
I definitely think it is worth having a go at making the part yourself if you already have the mount, as it is not too hard to get the fitment for basic functionality. The only hard part is strengthening the part once you have the functional fitment.
@@jamesandcamerawould you be able to tell me the size of adapter I need to make to match the e mount flange distance to the BMD ursa mini flange distance? I might try doing a 3d print, maybe I’ll use an m42 to e adapter I already have.
@@Philip-Dickinson-Studios sorry I can't tell you the flange depth. I agreed with a friend who worked with me on the R&D for it that we would keep it to ourselves.
However I can say it is not too hard to find if you can use a short helicoid or just short adjustable tube spacer to test different depths. Otherwise you could always do some math based off the size of my adapter in the video footage and get pretty close on your first try.
@@Philip-Dickinson-Studios I will also note that a M42-E adapter may be too deep.
Hi James...very interested in purchasing this adapter for my GH6.
I can also help you with any testing you might need for the m43 version. I have several SD, HD and 4K Canon and Fujinon b4 lenses at my disposal including 50x and 70x Fuji box lenses we can test it on. Thanks Anthony
Hey Anthony, get in touch with me by my email in the about section of the channel.
I will have the next batch of adapters ready in about a week 😊👍
@@jamesandcamera Hi James. Email sent from my spectravideo**************** email address. Look forward to hearing from you. Cheers Anthony
Thanks for your video, I have a Canon TV Zoom lens, J15x9.5B 9.5-143mm 1:1.8, I would like to mount this lens on my Panasonic GH5, Would this adapter work with this camera body and lens, and where can I purchase the adapter. Thanks for your help.
Hi Joaquin, thanks for your interest.
I can make the adapter to fit the Micro4/3 mount. As far as coverage of the sensor goes, you will need to find out for yourself if the GH5 has a S16 size scan mode or is able to clear image zoom to an equivalent crop for it to work.
The J15x9.5 is quite an old SD lens, I would recommend something newer for a better image quality. I have just tested a Fuji 7x7 from around the same time and it only really got decent image quality at f4 with a corrected adapter. Where newer SD lenses perform well from f2.8.
As far as buying the adapters are currently out of stock and I will build a new batch for people to buy to be ready September 2024.
I've reached out to you over Instagram Messenger, but I'm not sure you'll get it. I have 3 Black Magic Pocket Cinema 4k's (MFT mounts) and would like to control zoom and focus from the tripod handles. I am simply streaming content from my church and we are currently using photographic lenses & Cine Prime lenses. We would prefer to be able to zoom a shot in without having to switch to a different shot and having to focus manually, etc. Is this something your adapter and kit can help me to do? We are not streaming in 4k - really more like 720p due to our streaming platform limitations. Would love to see if this is our ticket.
Thanks Jacob, I see your message on Instagram in my requests. I will chat to you there 😊
@@jamesandcamera Mahalo from Hawaii!
Just curious I want to do something similar did you figure anything out to work with your workflow
@@jaymnonlyjapanese we did. What info would you like to know? We ended up getting a Fujinon B4 lens and an optical corrective adapter that we are using on our Black Magic Pocket Cinema 4k camera. We also got a remote zoom command with an adapter. The focus demands are quite expensive and we haven’t gone there yet. We are hoping there might be an inexpensive solution soon as many of them are $1000 or so. However, in our situation, we don’t need to change focus much and since the lens is parfocal, it really does most of what we need without a focus demand.
is there a 4/3" version for Panasonic GH5 II recording in 4K 60P?
Only a version that covers a S16 equivalent size of the sensor. No plans to make one that covers a full M4/3 sensor yet.
Great Video!!!, Good info for us B4 ENG lens Users ,,,, I Have the B4 15x9 KRS , older version Lens and have an adapter for the Panasonic AF101 camera, works fine, But I'm interested in using the lens on my Sony PMW F3, Fotodiox sells the adapter , though I don't think it has the Glass inside the adapter , and the super 35 Sensor will probably cause major Vignetting in the shots.....I also would like to use the lens on the Sony FS7Mk2 ... Any information would be greatly appreciated , Thanks Alex...........
Hey Alex, first I would need to know the exact model code (eg: Canon J16x8B4-...) of the lens to make sure it is worth you going through all the trouble 👍
The optical correcting adapters I customise can work with 2/3" B4 lenses and convert them with corrections and a slight image expansion to Sony E mount and other mirrorless mounts. There are other manufacturers who make more expensive optical adapters too such as IBE, MTF, Abakus, Sony and Canon.
I do NOT recommend Fotodiox for B4 adapters, from my experience I don't think they are optically correct and don't produce a clean enough image.
The adapter I customise is optically corrected and cleans up the image so that is like using on a native B4 3CCD camera. It suits S16 sensor sizes and can cover 98% of a S35 sensor when using a lenses inbuilt doubler. It is perfectly suited to FS7/FS5/FX9 with their S16 center scan mode and S35 capture mode.
Hope that helps 😊👌
