Well, I have the 50mm f2.5 Compact Macro, and my feelings are mixed. It is extremely sharp around f4 in the middle, but you need f8 to get perfect corners. The AF is quite inconsistent, the vignetting is a disaster until f5.6 minimum. But I use it for architecture, and it has no distortion at all, combined to an excellent sharpness until f16, good at f22 (only f32 is really bad). The mechanics are awful too, nasty focus, and it gives only 1:2 macro. The only thing that can't be beaten is the price, I got it for 220 Euro.
This is one lens Canon should update in an emergency. Even the old Nikkor 55mm AIS beats the hell out of it.
I could be interested in the 35 f1.4, depending on the tests, I will wait until I can compare the f2 IS and the 1.4 II though.
For the 14-24mm, I have no urgent need, but I would like to see how it compares to Nikon's, hoping it won't be 3.5k.
