I have the FD 35mm f/2.0 S.S.C converted to MD mount (weird eh!) and I think the sharpness is quite good wide open, I don't know how it is stopped down as it does not stop down after I converted it. But I am sure it's very good, as all primes are. I'm pretty sure not much has changed with the EF version of this lens.
Here is a sample.
100% crop from above.
The forums upload method softens the image quite a bit. Do I need to host the image somewhere else or is there a walkaround?
I think the biggest problem with this lens is the bokeh, it's not bad just not outstanding. In less busy backgrounds it's not a problem, although if you had a better lens I think you would still tell a difference.
Cheers,
John.
