| comment: | This lens is a terrific performer on the FF a850. It allows for great coverage and appears to have no trouble with light fall-off or vignetting (except see below). The distortion is to be expected on a lens of this type, but I have either used it to my advantage or corrected it in PTLens. I will probably order the grid viewing screen for the a850 as the multiple lines will help in keeping the horizon straight. It is unquestionably a very sharp lens in the center and out at the corners. Maybe f2.8 might be a little soft but f4-8 is just outstanding. I have not tried it on the a700 simply because I have the CZ 16-80 to handle the focal range. On full-frame, it is, of course, a little wider than the 16mm on crop sensor. Very nice to have this angle of view. It is small and light. I have experimented with a polarizer and get a slight bit of vignetting. Using this filter on such a wide angle lens can also be problematic, because the tone value of the sky is affected by the angle to the sun. It is becoming a favorite on the a850; however, you must slow down and take your time in composing. Otherwise I end up with some very sloppy shots. |
