Useful video! Only constant chomping is annoying.
i really appreciate the video, but next time please stop chewing before making video
Archontasius yes, the chewing is very annoying
that noise gave me ideas about sticking a fork in my ear
I stopped watching after 2 mins, can't stand the sound of someone chewing.
Thanks for posting, just found a Jupiter 8 sitting in my father's cabinet, and always wondered why he did not keep with the rest of his camera stuff. Gonna try and take care of it now.
Great video ! Everything gets shown and explained. Perfect.
(Info for future videos: _"Screwdriver"_ is the tool you're using to remove and fix the screws; the tiny threaded metallic parts you removed and then put back, are simply called _"screws"_.)
iBug Thank you!
Thank you for this video, you make it look so easy putting the screws back into the lens. The disassembly is the easy part the difficult part is getting those screws back into the lens body with out them pinging off in different directions. I lost one on the carpet and spent 30 mins trying to find it with a magnet, they are so tiny (smaller than a pin head) and really hard to find if you loose one from where your'e working. Great video I followed every thing you did and it now works with the correct position of the aperture ring.
Thank you for your input!
Very good video, thank you. I have two Jupiter 8 lens. One is Contax mount for my Kiev 4, the other on my Zorki 4 is Lecia screw mount. Both have some dust particles internally.
Oh, you are kosbik! I bought a lens from you before :)
You're welcome :)
Awesome! It is not so obvious how to get to the front element so this was really useful. Thank you!!
Glad it was helpful!
Thank you very much! It is simpler than I thought.
Thank you for bringing this excellent tutorial to TH-cam.
Glad it was helpful!
great video - perfect level of information.
Nice demonstration, thank you!
very clear demo on how to do, thank you..
You're wecome!
Excellent video.Many thanks.
Hello. In this and your other videos about cleaning and lubricating lenses, you can safely disassemble the lens blocks and assemble them back just like that without adjusting the optical axis.
If you read various articles on the repair and cleaning of lenses, they write that disassembling the lens blocks inevitably leads to a violation of the optical axis, and the lens after such an intervention
will no longer be sharp enough as it could be. Also in Soviet books on the repair of photographic equipment, such as Meisenberg or Vishnevsky, they write that it is undesirable to remove the front optical element, probably for the same reason.
Therefore, to you as a master and author of many videos, please. To clarify this point, is it still necessary to align the optical axis after disassembly or not, if necessary, do you do it and on what equipment?
Or maybe this phenomenon does not appear on all lenses, depending on the design?
best regards.
Excellent video
Hi, very helpfull video! Thank's!
Great video! Thanks for the tips
Thank you very much.
Great to see how to cleaning up the Jupiter-8. I've just bought one of if form eBay, also a Jupiter-3 lens as well.
By the way, can I use the same steps for Jupiter-3 lens also?
Unfortunately, I cannot find any information on how to cleaning its optical parts for Jupiter-3
My Jupiter 8 lens is just like yours, but it feels very loose, like it is falling apart (not when on the camera; just the lens by itself). If I handle the lens, I can feel and hear some parts wiggle. I tightened all the screws, even some which are hidden, and nothing helps. Do some copies of this lens permanently have this problem? I’m wondering if maybe the focus ring was built too large for the lens barrel. Anyway please let me know if you have fixed this before
Great video. I have found on Rangefinder forum that Iron Glass was able to modify the Iris blades to be 18 rounded blades instead of typical 9. They don’t do it anymore. Do you know how would one be able to do that themself?
One can't do it by itself, unless possessing milling/drilling equipment. But frankly speaking there is no need in doing that, as original 9 blades is enough to have a rounded bokeh
I got a Jupiter-8 lens, with just a few dust specs between lenses that don't really affect the pictures but I was wondering if you know how can I polishit or clean the aluminium of the body without damaging it and, if possible, without taking it apart.
Thanks
without taking it apart it is not possible
Hello, I have a problem with the aperture ring on this lens. When I want to fully open it - the marker doesnt stop on F2 number but goes beyond.
Same goes when I want to choose f22 - the marker of the selected aperture ends between f22 and f16
Is there a way how to fix it ? I have the silver second generation just like you
What are your recommended cleaning solutions for these older lenses that may have fungus, and/or haze? Would regular lens cleaning solution work, or alcohol, peroxide, or lighter fluid?
Best solution to clean fungus-ammonium chloride. This is strong organic solvent, can be found, at least here, in drugstores
Smallest screws are 0.8mm flat (slotted) screws. You can buy a small kit on ebay. Many precision screwdriver kits only go down to 1mm but this is too big. Make sure you get one that gets down to 0.8mm
example here-

Thank you for sharing this, it is useful info
Discombobulated Thank you.
Thank you for this video. I have a Jupiter 8 Kiev mount, which is pretty unsharp on the left side wide open. the right side is sharp. Can I calibrate this?
i'm afraid you can't
Hi, what kind of alcohol do you use? Isopropyl alcohol? Thanks!
This is a pure medical alcohol you can easely find in a drugstore
Hi Roman, are replacement screws for the tiny ones available anywhere?
i know only one place to get them- from another lens bought in 'parts or repair condition'
What solvents can be used to dissolve optical cement?
Hi. Any idea how to repair the focusing ring on the black version, it somehow became loose. Thanks
try to tighten 3 tiny screws on the sides of focus ring. This might help
Can you please tell me what is the size of the screw to take the first 3 screws of the lens?
My tools are too big for those 3.
Thank you!
Great Tutorials!
You can buy small screwdriver sets. They are mostly used for glasses, watches and smartphones...you can find them anywhere...

Can you please discover the trick How to adjust this lens for infinity on canon eos 6d (for example) ?
+Kaspars Brambergs It is not possible. This lens is for rangefinder(mirrorless) cameras only.
Ok, Thank You, but how about Sony a6000 ?(mirrorless / crop sensor / e-mount)
+ я ищу Юпитер-9 алуминий. есть ли увас на продажу хорошый ексемплар, который вы рекоммендуите на вашем ebay? И как приобрестьи? Рига. спасибо.

Great, thank You! Let's try!
Can you teach us how to shim it to be used on Leica?
+Simon Tay On old leicas with thread mount it fits without any problems. On leica m cameras adapter is needed.
You wanna use a $40 junk lens on a $7,000 camera? okay...
@@JeremyGalloway Simon wants to use a fine Zeiss Sonnar design on just another shutter and film holder. Good idea, Simon!
