Excerpt: I love nature photography and this lens is a wonderful addition to my kit. The SSM technology is really great. I have the Sony a77ii with APS-C sensor, so I have a little longer reach when I am fully zoomed in to my subject.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Strong Construction
Excerpt: Had to return due to a peace being loose. But I did get to take a couple pictures with it & they looked great. A little soft at full zoom & was a bit heaver them my Tamron 18-270. But over all could be a bit better for the price.
Summary: I really wanted to give a more in-depth review of this lens, but after eight months, I feel that I have not taken enough pictures to cover all aspects of this lens. So, I only give some of my personal experience and observations with this lens.
Excerpt: I absolutely love the lens. It is exactly what I expected. Sony always produces high quality gear. f/4.5 operates poorly in low light, but does great when you boost the iso. Works amazing in reasonably lit settings, even sharper with a tripod.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Rugged, Strong Construction
Summary: I took this lens on a trip to Costa Rica and I have only a few comments to add to the very thoughtful posted by others, most of which are on target and consistent with my own limited experience with this lens (I took a few thousand shots on this trip). First, the lens performs as advertised.
Excerpt: Great pics, great color, great sharpness. I heard grumblings about focus speed, but I'm not seeing that at all. Focuses as fast as any other lens I have. extremely quiet. I sure would like to have another stop or two though. It would be worth an extra $200 and make low light stuff much better.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Nice Bokeh
