Are any of these photos cropped? I was thinking of getting an FD Lens Turbo but many people have said that you only get good sharpness in the 1/3rd around the center.

I have a recently acquired 24mm f2 FD . From what I have read, the corners will be no better than the SEL 16 pancake and probably worse with the LT

I haven't done a lot of shooting at 24mm + LT, but with good FDn's - 35/2, 50/1.4, 100/2.8 - I get good sharpness to the edges, much better than i expected to be honest and i would have happily lived with soft edges. I guess the FDn's are just that good! The robin is almost 100% crop, but the others aren't, except the portrait architectural shot, which had a very minor crop around +7 barrel distortion correction to straighten the lines - you can see it's sharp right into the corner at f5.6 on the FDn 50/1.4!

OK, thanks for the reply.  It sounds like like the LT is very lens specific.  Many seem to have good success with it using the 50mm f1.4.  I used to have the SSC version of this lens.  Never really like 50mm on APS-C I find it both too long and too short but would be great with LT.

I might see if I can get a used LT to try out then.  I'd like to try it with my 85mm as well.  I don't think it will work well with the 24mm f2.

I think LT and SB performance does depend a bit on the lens quality. I should know for sure shortly.
