Some are definitely better than others. No worries, the same is true for other lines like Nikon also. You have a great lens in the 50mm f3.5 Macro. I have found the sharpest lenses in the FD lineup to be:
FD 85mm f1.2 L
FD 100mm f2.8 in Breach-Lock
FD 50mm f3.5 Macro in Breach-Lock
FD 24mm f2
I'm sure there are other excellent lenses in the FD lineup. I also like the Canon 35mm f2 Concave in Breach-Lock, but I haven't found it to be as razor-sharp as the ones I listed above. The macro and the 100mm f2.8 can be found at such reasonable prices I'd consider them "best buys". The 85mm f1.2L is so sharp it can beat a Leica 90mm APO Summicron. But you pay for it in weight and $. Other lenses are downright pedestrian. I've never been a fan of the FD 50mm f1.4 ... I've used it, but I far prefer the 55mm f1.2 Pre-Aspherical. And I prefer the f3.5 macro to either of those. Go figure. At some point you have to just try them out and judge for yourself.
