Hi Everyone 

As usual I am singing the praises of the 40mm Rokkor to a friend, who is interested to obtain a copy and file the flange to bring up 35mm framelines instead of the 50mm fraemlines it usually brings up on m bodies.

I have not filed mine because I also use CLE and want it to continue to bring correct framelines with CLE...  Does anyone have a filed copy that they could post photos of so I can show my friend what he needs to do and where ?  

Thanks in advance

I've done this to a few- but i am not at home currently. but this is what I followed when I did it:

note the comment below the original post:

 

"You have taken off way more metal than needs to be removed. You don't need to take off a big corner of metal - just a few strokes with a small needle file on the shoulder of the flange will do the job. "

I've done it with a 40mm CV lens and only a tiny amount of metal needs to be removed.

Thanks @jacques, thanks @250swb I will pass this on.   I’m hoping to find a cheap second copy at some point also and have one for my M’s without changing my CLE  copy
