I paid a small fortune for this lens,and being that it's really the only one in it's class, I had no choice. I'm not easily blown away, so it's not a big surprise to say I'm not blown away--it's exactly as I would have expected. It's a big, heavy, well made super wide angle lens. The distortion of objects is pretty much what I expected. The focus is silent, but somehow feels a bit slow especially being that it doesn't use Sony's new hybrid auto focus--a real disappointment considering how long I've waited to have a Sony full frame and how much money I paid (I understand future updates will address compatibility issues.)At 2.8, depth of field is shockingly shallow and hard to use. The fault might be entirely mine, but for the moment the lens doesn't seem to be very sharp, and seems challenged in focusing on images at close or medium distances. Overall I'm fairly happy, but like all high end gear it doesn't do any magic by itself. You've got to know what you're doing, practice, test and work out how to get the best results from this lens. One thing that did surprise me right out of the box is the build quality, it feels like a tank and weighs about as much.
I had to return my copy as it was not all that sharp. For the cost of this lens it should of produce sharper pictures.
