Excerpt: I'm using this lens to take outdoor wildlife pictures.<br /><br />I'm loving the image quality from this lens paired with the A99.<br /><br />Focus speed is pretty good but I understand that the G2 version of this lens has faster focus. I haven't tried that lens yet but using this lens I can see how they could have sped it up. It can be a tad slow to focus sometimes but overall the focus is pretty fast and it is accurate from what I've seen so far.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Rugged, Strong Construction
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.
Excerpt: I am an avid nature and wildlife photographer. In my time in the field I have used both a Sigma 120 -400 and a Nikon 80-400. I was completely unsatisfied with the Nikon product but generally was willing to settle for the results I got from the Sigma product. But while at a local camera club, I got to try the Sony 70-400 G lens and that lens immediately caught my eye. I have now owned the lens for over one year. During that time it has become my "go to" lens.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Rugged, Strong Construction
Awesome lens -- super SHARP even wide open at 400mm
21 February 2013
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.
