Help: Does this ruin my lens? Broken fin/prong on back of Nikkor 50mm 1.2 ai-s

[vi0lat0r]

Hello - i just noticed i must have accidentally broken this prong off the back of my 50mm nikon nikkor f1.2 ai-s lens. To me, the prong looks like it prevents the rear element of the lens from being scratched if rolled over and possibly extra support for being bumped? The lens still fits ultra tight into the mount i just have not had any time to film test yet, and i appreciate any of your help in feedback!



I have copied a link of my lens, and some screenshots of some non-broken versions.

It's a tab made for mechanically transferring the len's maximum aperture to certain cameras. I don't think any modern DSLRs use it.

That makes sense! I think it has to do with P / S modes and matrix metering cameras. I use this lens on my F3/Fm2n... so hopefully no issues!
