I have a Canon FD 50 mm 1.4 lens (New style). It is super fast and I love it.
Is there a way to simply attach this to an EOS body with an adaptor and not have to modify anything?
I ask as I now have this lens working with a modified adaptor and wonder if I did this the hard way.
I took my lens, I then enabled Manual Aperture (py pushing in the pins and twisting the back around like this video http://www.youtube.com/watch?v=juGX1XyZ6WI)
I then used the toothpick method to leave the lens in a state where I could change aperture from the lens aperture ring
I then purchased an FD to EOS adaptor with glass inset to allow focus at infinity, Focus confirm
I found that with manual aperture set, I could not use the FD to EOS adaptor as rotating the back of the lens exposed little metal lugs that prevented the FD to EOS adaptor mating. If I rotate everything back, the adaptor fits but at a stuck aperture I cant change.
I then used a hacksaw to cut additional grooves into the adaptor to slide over the newly exposed metal lugs and got it to mate.
As this removed the ability for the adaptor to stay attached (It would not lock on), I then had to use cloth tape to hold the lens and adaptor together.
Now I can attach my lens to the EOS camera. I can set the Aperture via the dial, I have infinity focus and focus confirm but this was a lot of work just so I could get Manual Aperture.
The default behaviour without the manual mod is either wide open or almost closed with an inability to be changed.
I don't mind so much as I have a working design and I only had to pay $25 for the adaptor and had to spend some time to cut it up but I wanted to get other peoples feedback.
