FD lens silver lens mount replacement.

Hi all. I need to replace the silver lens mount "plate" on my 80-200 mm FD bayonet mount lens. I have an

extra 50mm bayonet mount that I can cannibalize for the replacement plate. There are 3 screws that (seem

to) hold the silver plate onto the lens. Is it as simple as removing the 3 screws, slide the damaged plate out,

slide the good plate back in and replace the screws?

Would there be any "surprises" waiting for me when I remove the 3 screws and pull the plate out?

 

Thanks for the advice...

 

Gary.

<p>I assume you're referring to the chrome plated breech ring that you rotate after mating the lens to the camera. Removing this ring is a very tricky procedure if you've never done one before. Read my comments in the following threads:</p>

<p>Proceed at your own risk.</p>

Gordon. No. Its a bayonet mount. I think that is the term. You line up the red dot on the lens

and camera and turn the lens about 1/4 turn cw until it locks. Im looking to replace the silver

mating surface on the lens. It looks like its held in place by 3 screws.

<p>Sounds like you have the all-black FD "NEW" style lens, aka FDn.</p>

<p>For those who want to be in the know and possibly don't: These lenses were introduced for the F-1N (F-1 "NEW") camera.</p>

<p>These lenses have the aperture rings slightly rearward of the silver breech lock ring lenses. The re-positioning of the aperture scales was for viewing the lens aperture set on the lens, via a viewing window in the bottom front side of the F-1N camera's prism.</p>

<p>The newer FDn lenses are interchangeable with the older style breech lock ring type lenses, and can be used on the A-1, AE, EF and F series bodies of that period.</p>

<p>The mounting method you describe is used with this newer FDn lens type where you rotate the lens body to lock, as you have noted the specific mounting method.<br /> <br />Can anyone help Gary with an FDn lens plate replacement?</p>

Keith. All u say is spot on. I use the lens on a Canon F1-N (NEW). Any help would be

appreciated. Worst comes to worst, I bought a "beater " 50mm FD lens on ebay....I guess I'll see

what happens when one removes those 3 screws :)

<p>Please keep us updated.</p>

Exit stage left. Scratch plan B. I think I'm going with

this plan.

<p>Good Tech you chose. Steve has done very difficult work for me in the past and he can practically rebuild Canon FD items in his sleep.</p>

Keith. Thanks. The 80-200 f4 l is probably not a wise

choice for a "first timer" repair. I'll practice on that 50

mm beater lens i bought.

Got my 80-200 f4 lens back from Steve. Needless to say a fabulous job done. From the time I

mailed it to Steve and received it back was exactly 1 week. He even threw a front lens cap on it

for me. Thanks Steve.
