Thanks for the tutorial, very helpful! In one of my Contax, I can hear something rattling inside the lens, almost like a loose ball bearing that is moving around on a track. I de-clicked the lens (ie deliberately removed the BB) and it definitely is not left inside the lens. Any idea what might be making the sound? Thanks again
thanks. my aperture ring no longer changes the f stop. it's just permanently on 1.4. i can spin the apeture ring but it's not linked to the blades anymore
Probably the mechanical connection jumped out, or maybe it is oil on the blades, which seems to be a common issue with this lens. If you follow the tutorial you can most probably fix the issue. Cheers.
Hi, I lost the aperture bearing ball and spring during the disassembly. Do you have the dimensions for the spring and the bearing ball? Thanks in advance
That's bad luck :( I don't have the lens anymore, so I cannot tell you the dimensions. You can measure the hole and take a smaller size for the spring, and for the ball, you can revocer one from a pen. Cheers.
Interesting that all the various lens parts and components are called "here". And too much hand touching of parts. You need to practice how to manipulate the parts with tweezers, to avoid putting oils from your hand on the parts, before reassembly. Do not use toilet paper for anything, as it has the potential to leave behind lint. There are so many microfiber cloths you can use. Lastly, you need to re-lubricate the parts you cleaned, or the helicoids will wear out as you use the lens, because aluminum (aluminium) is a very soft metal that will wear fast, if not lubricated correctly. Overall, it was a useful video.
Thx for this tutorial ! It helps me a lot !
Great, glad it helps ! Don't forget to tell your friends about this channel. Cheers.

Hard to say, is the return spring of the diaphragm working and the lens has no play? Regards.
@@diyextravaganza Thanks for the reply! Yeah, everything seems to function correctly. It's really odd
@@birdonfiremedia Hard to say, maybe a slightly loose lens.
Beautiful
Thanks !

@@diyextravaganza thanks. there is no oil on the blades. think i can open it from the front to reattach the connection?
@@astrosecret7260 yeah, just follow the steps in the tutorial and you should be fine. Cheers.
@@astrosecret7260 were you able to fix this? having the same issue

Thanks for the feedback, I'll keep it in mind for future videos.
