|comment:||Those are my only wide-angle lenses, bought primary for the indoor architecture work and landscape. I also tend to do portraits with them - wide lenses give a very different and stunning results, even on my APS-C body.|
Those lenses are sharp, and when correctly used sharp from 2.8, thought read on about AF.
What I really dont like is the AF - it seems to be back-focusing and I cant verify it on my A55. Because of focal length this makes pictures less sharp that they should be - this is especial visible when taking photos of group of people. I go MF a lot just to correct for it. It seems that problem is gone by ~F7.By this time DOP is huge enough to cover the problem. I also tried short focusing or per-focusing a few times before I take a shot.
Wide open they are not as sharp as 50/1.4 but once step down, they start to match. In low light they behave different to 50/1.4 or 35/1.8 giving a softer image - useful for some.
Used with flash they provide stunning results - AF problem is much less visible and I just love sharpness and colors
Overall, is one of my most used lenses, providing me with some really stunning photos. If only AF would be less temperamental...
