It's too early to say! in a line for each..
Instantly loving the output colours and sharpness of the 16-35mm 2.8 GM
24-70 hasn't wow'ed me, but it seems a solid performer
70-200 also does the job, I think like the 24-70 I have nothing to complain about - they are everything I need in a couple of work horse zooms, I am very happy with them.
I am happy with them, 24-70 performed so well in a play rehearsal, quality of images were great.
100-400 has been used the most I think because I've been playing with it and nature quite a bit, as I haven't had the chance for a while to do this kind of photography. That has excellent IQ, particularly as it's a zoom - for all i know the 70-200 IQ is just as good, just I haven't used it at low iso and pixel peeped in the same way.
85mm 1.4 is damn nice..
35mm 1.4 was pretty good too but hasn't had chance to shine yet.. I'm noticing the CA cropping up
Not used the 50 1.4 yet
35mm 2.8 not writing home about this one
Oh and 90mm 2.8 looks great so far, as I'd hope from a properly priced macro lens - Yuffie's hair looks like hard bristles!
you bet she is
