Summary: This lens is really sharp. It's a little different from a lower end telephoto because you have to make some adjustments manually to start to get it into focus. But, once you are used to that, it's awesome in the clarity. I just shot with it for two weeks in Yellowstone Park, and was able to get really super sharp shots of elk, buffalo, bears, rams, and landscapes.
Summary: Bought this lens to use with my new A7R (and adapter) and this lens is simply amazing. Granted depending on what you are shooting you really need a tripod to stabilize the camera I got some terrific shot just hand held. A must own.
Summary: Very crisp picture and quick to auto focus. Great tool in my bag for getting closeups. Travels well but is not a light weight. She will let you know she is in your bag. I also carry a SAL 16-50 2.8. Those 2 give me the range and clarity for any occasion. Glad i have it.
Good during day light in the open but over priced.

Summary: + 3 weeks since i got it from amazon for $897. + Very well built. + Sharp images in the open if light is good. + Fast focus without noise . - A little bit heavy. - Just 4.5 aperture. - Over priced, as usual with sony's good quality products. - Must used with a tripod if maximum focal length used.
