Summary: The Sony SAL70400G 70-400mm f/4-5.6 SSM lens is a great wildlife lens for those using the Sony line of A mount DSLR cameras. It gives very sharp images and focuses quickly and quietly. If your subject moves slightly before you can snap the picture, you can adjust the focus without switching over to manual mode like a lot of lenses.
Summary: There is no comparison between the "G" series lenses and those you would buy over the counter at the local big box store. Then again the price difference between this lense and a kit lense is substantially different as well. Lots of comments have been made about this lense and the weight. Believe those comments. The lense is heavy and isn't really a good 'walking around' lense.
Summary: I have used this for capturing pictures of People and landscape. It does the job well. Cant help to think that Sony Glass would be a little better. It just starts me thinking that I want a fixed length prime with more light gathering capabilities, that of course would be priced at the same point as a used car. I can get more utility out of a used car than a lens.
Awesome lens -- super SHARP even wide open at 400mm

Summary: No need to stop this lens down to gain sharpness, it maintains tack-sharp image at the extremes. I've owned this lens for over 3 years; purchased it February 2010 from Amazon for $1600 (yes, Sony has upped the price a couple of times since). This lens replaced my old Minolta 100-400, which was a "good" lens, but was somewhat disappointing at 400mm unless stopped down. This lens will not disappoint!! Is sharp at all focal lengths.
Summary: I bought this in like November 2011, and as the winter started to get colder, I had to put the lens and camera stuff away as I'm not much of a winter shooter. That being said, I haven't used this lens too much, but of the times I did get to use it, I could not believe how much quality was in this thing. I was able to count the shingles on a pine cone on a 100 foot tree that was 250 feet from my house with the sun behind the tree.
