I totally agree. If I was in the market for a fast 35mm prime then 9mm wouldn't make any difference to me at all. However, I've been a long term user of a ef 35mm f1.4L mk1. Sure the newer mk2 is superior in every regard (including price). However, all that extra sharpness and faster AF and built quality caused the lens to be a lot heavier and physically larger. Comparing a rf 35mm f1.4L to a ef 35mm f1.4L mk1 is like a night and day handling experience.
On a different note, the new rf 100mm IS L Macro...geeze..sure it's got a few interesting new features...but the size of that thing compared to the EF version!
