I have used the 28-135 on my A900, though I only used it in the range 28-70, where I found it to be quite sharp. I did find a bit of CA (colour fringing - see my post earlier today!). I haven't tried the 28-85, but the later 24-85 I found OK but inferior.
The 28-135 does not seem to be as sharp as my more recently acquired used Minolta 35mm f2.0 or 28mm f2.0, or the 50mm RS f1.4 which I had for some time. However, I believe the f2.0 lenses (now discountued, alas!) are fairly exceptional and the going price for each is greater than for the 28-135.
I haven't tried the Sony CZ 24-70 which is the obvious choice if you can afford it and if you don't already have suitable glass, but I think you will be pleased with the results you get from the 28-135 on FF, assuming it is a good example, and that the image quality of the A850 is not significatly inferior to the A900.
If expense is a consideration, it might also be worth canvassing the opinions of those with in-depth knowledge of the Alpha system as to whether it would be better to buy an A850 to use with your existing lenses, or an A700 (assuming you don't already have one!) + decent wide-angle zoom (e.g. CZ16-80?).

Once the A850 is available, I may just take my zooms and a memory card to the local dealer and run off a few frames to see how these old lenses fare on the 24MP sensor.
Thanks for the reply. So it seems the the 28-135 will do tolerably well.
