This is one of my favorite vintage lenses (I own two). I was not aware that these were not radioactive though ...the glass on mine is kinda "yellowish" so I always assumed they were yellow-tinted (thorium) lenses. Anyhow, thank you for this tutorial. It might come handy in the future. I have only tried to dismantle and clean an old Helios 44 once which in my opinion is a great lens for a beginner to experiment (cheap, readily available everywhere and easy to dismantle lens). I used an ammoniacal base especially suitable for crystals, bright and glazed surfaces. It dries quickly but I might look up to some of the benefits of using ethanol instead.
I love lens disassembly and cleaning optics, it's truly is quite meditative for me. At least until I start to fiddle around with the helicoid and inevitably end up incredibly frustrated trying to out it back together, lol. Also, I have some official Konica and Nikon lens repair manuals I purchased a while back and most of them indicate that the prescribed solvent for the Loctite glue they used on these is 100% pure methanol. Acetone works quite well, but I find that it can leave behind a film that sucks to clean up, whereas the methanol releases the adhesive much quicker with minimal mess. It's a bit more expensive but I found it to be worth it. I have a lot of old lens repair manuals on rolls of Microfiche Film. I've been meaning to scan them all to PDF and upload them to my Google drive. Whenever I get around to that I'll send you a download link for them if you'd like.
I keep that one for when I will try that ! Very good advices. 👍 You can do that way with all vintage lenses ? I am more interested by M mount lenses, it’s doable to ?
Dude, I have the 50mm f1.4 and I took it apart, literally unscrewed everything down to the individual pieces because it was loose anyways. For the life of me, I cannot get the F**KER back together. There's these two metal tabs on the front half that I think are supposed to mate SOMEHOW with the rear half of the assembly, but it will NOT lock in place. Any suggestions?
@@Noealz ive boughy so many lenses, gotta learn the term! tho as long as its now balsam separation, any lens can be saved! balsam is the lens glue between optical block, if this goes bad, theres nothing to really fix it

Oh the lens is kinda yellowish I assume because of the leaded glass they used to use :)
Kind of liking these vibes of the overhead shot Noe!
I'll do them whenever I get a chance!

Oh man that would be amazing - thank you : )
@@Noealz welcome!
Can you share with us?
Thanks a lot! ... I have the auto takumar 55mm f2 with the same problem, now I know how to clean it :D
it is pretty simple once you get that rubber grip tool :)
Awesome video!🦋💜
Thank you very much!

You can do with any vintage lens - but they are all built differently so they are opened differently : )
@@Noealz If I can find dirty cheap old lenses I will try that ! 😋

Oh super sorry - this is the first Yashica lens I take apart : (
Worth noting if you're looking for the opening tool for lenses search for "lens wrench" on amazon etc.
haha right i dont know the proper terms
lens spanner wrench . Neewer sell decent models at good prices .
Calipers are fine too.
@@lusoclassic3142 100% on a pair of sturdy straight point vintage calipers. Pretty cheap on eBay and after a quick wash they work amazingly well.
There's the autotakumars which are real similar to this! All really nice
I don't have one of those super old ones sadly :(
This Yashinon is a copy of the Tominon 5cm f2, and the Auto Takumar 55mm f2 is nearly identical.
Interesting video!
I'm not patient enough for this kind of job :-)
Patience is a virtue : )
Question: What is the difference between Neon Noir and Cyberpunk?
cyberpunk is an ideology, neon noir is just a name to a style of high contrast with neon lights
@@Noealz Thank you!
What Camera do you use?
Who knows :) Not important!
This was like I was watching the South Korean Big Clive
큰 클라이브 ㅋㅋㅋ ^_^
haha I am glad you watched : )
언제나 감사 좋은 비데오
thank you very much!
its called hazing, its grease from the helicoid, the focus tread oil evaporating from heating up in the summer multiple time through out the years
Ah cool, it is good to know the actual term : )
