I haven't noted that in any reviews or tests ?
I own all three lenses in the Canon version, and while I think the 85L is better than the CZ 85mm, it is only because of the extra stop of speed and the better focus. The 135mm f/1.8 is better than the 135L. The 135mm CZ is just an outstanding lens. I have an older 24-70L and it has always been a little on the soft side. The CZ 24-70 is the sharpest of all the 24-70 lenses with the Nikon a close second. The Olympus 14-35 is sharper, but technically they are different focal lengths that provide the same FoV. The only thing about the CZ 24-70 is the bokeh can be a bit harsh.
One advantage that all three of the Sony lenses have is that they are all image stabilized on the A900, where as none of my Canon primes are stabilized.
Sony has some holes in their lens lineup, but those three focal lengths are my bread and butter, and Sony has done an excellent job with them. I'm not fond of the slow noisy screw drive AF, but it seems no manufacturer does everything right.
