    I have been reading a fair amount about the FL lenses because of my purchase of the 2 great lenses that have been mentioned here. Some where it said the apature will remain open until the shutter is activated. Keep checking the links from Wicopedia they might have better info than I do.

    Do the FD lenses stop down? If they don't it's camera linkage not lens.

    The FL lenses didn't have the interlock for the breech lock or open aperture linkages.
    If you set the f to 16 & move the lever at the back of the lens it should stop down. If it doesn't 99:1 it's oily blades. When it was put away it most likely worked. This is something that happens over time.

    Yes, the FL lenses provide for full-aperture viewing, but not metering. You have to stop down the lens to meter the scene, but you don't have to leave it stopped down when taking the photo.

    Thanks for the info. It is hard to line up information on old lenses because you run into so many different options etc on the lenses. Turns out that that was the way I was doing it. I just experimented on running my FL 55mm f/1.2 on my A1 today but I forgot that there was colour film in it so I'll have to wait to get it processed.

    You know, now that I think about it a bit more, I think I may have misspoke, er, mistyped. Dang it, I wish I had an FL lens handy. Most Canon FL lenses have a separate ring that allows the user to open and close the iris without having to adjust the aperture ring, much like the way many "preset" lenses operate. This is to aid in focusing ease. So, when you push in the stop down lever, and click it into place, the lens aperture is now stopped down, and you can meter the scene. You must leave it like this when you take the photo. That separate ring, you can use to momentarily open up the aperture to insure correct focus, then you turn the ring back and take the picture. Sorry about the mistake there. It's been over 20 years since I've shot with an FL lens.

    Yes it would seem that the FL lenses on FD bodies are a combination that has a few variables. I have tried it stopped down but I won't know the outcome until I shoot the whole roll and develop it. I not going to be too much more experimenting until I find out.

    Took the FL off the A1 FD and put FL back on the FT. So everything will be OK

    *The earliest versions had to be cocked like this, the later versions not so.
    You must leave it like this when you take the photo. * Not so.

    That separate ring, you can use to momentarily open up the aperture to insure correct focus, then you turn the ring back and take the picture.

    *Also not so. The stop down mechanism in the camera fully engages with the stop down lever in the lens. The meter linkage does not. that's why you need to stop the lens down manually to meter.

    John, I was referring specifically to using FL lenses on FD cameras. I probably should have been more clear. What I wrote above agrees with both my Canon AE-1 and AE-1 Program user manuals.

    I just acquired a manual on the FT QL and I see my 2 lenses are different. On one of them there is a separate ring. One has a manual aperture ring as well as the preset. The other has the automatic ring as well manual. That might be one of the problems setting apature. So different instructions for each kind of FL lens. I see that it was explained before but not the FULL description that is in the manual. Like the saying goes if all else fails read the manual. Worked for me anyways.
