>>3011728You could probably get an F3 and an AiS 35/2 for the same price as the oly lense.
But really, I'd say the 2.8 is probably pretty good. Usually simpler, slower lenses exhibit fewer abberations like CA and distortion, as well as higher contrast.
I use an FD 35/2.8 and it is razor fucking sharp, even on digi, but they're quite different designs. The canon has 6 elements to the oly's 7.
