Well made, but a little soft

Excerpt: I was impressed with the construction of this unit. It was solid, albeit a bit heavy, and operated smoothly. Auto-focus and image stabilization worked well. Image quality was quite sharp from 120mm - 300mm, but then got a bit soft from there out to 400mm. I photograph wildlife, especially eagles, and spend most of my time in the 300 - 400mm neighborhood. I need something sharper in this range. I have run into a few folks who own the Sigma 50 - 500 and love it.
Pros: Fast / accurate auto-focus, Rugged, Strong Construction
Excerpt: It seemed to be a "higer quality" lens than a kit lens.... Tested it out in different lighting situations. The image stablization was great though. However, I've had kit lenses with better image quality out the box.It also had really bad zoom creep that I could not deal with. Not sure if it was me or the lens. Either way I returned and for a Cannon 300mm f/4 becuase it was only $200 more than this lens.
Pros: Fast / accurate auto-focus, Image stabilization, Rugged, Strong Construction, Well Balanced Weight
Summary: Purchased this knowing that it's a value-priced and performance item. Used specifically to shoot for just ONE customer - pro baseball team. It's a little soft at the wide apertures and in the corners, but again - a great value for this sort of lens. Since my images aren't enlarged and often a used for team website, it's perfectly acceptable. If i shot sport year-round I'd probably opt - or perhaps NOT! - for the more expensive and better-performing Nikon 80-400.
Summary: Purchased this lens after going in the store to buy the Canon 100-400 zoom. Had great build quality and I wasn't crazy about the push pull zoom system of the Canon, not to mention is is a lot cheaper. Well, you dont get something for nothing. I bought this for wildlife photography. The lens is very sharp in the wide range..120mm. Actually some of the sharpest photos I've taken at that range was with this lens. At 400mm it's a very different story..
Summary: I was excited to get this new Lens I have to say overall even with the issues I had with it I like the pictures it took and the Feel of it but right out of the box it was not working I was gettting Error "F" meaning the Lens was not connecting with the camera and it got worse as I used it more. I sent to back to Beach Camera I do miss the lens.
Excerpt: This lens appears to be constructed very well. The zoom and focus rings work nicely - not too tight or loose. The included carrying case, straps, and lens hood are also appreciated. The lens performance, however, is not all that great. I am a hobby shooter and don't have super expectations for crisp shots, but I am not able to get many sharp shots with this lens. At the lower zooms - to about 200 - it is pretty decent.
Summary: I bought this lens after returning a 150-500 for back and front focusing issues on a Nikon D700. Well, the 120-400 suffered from the same problems. My copy had bad back focus at 400mm. Using the D700's AF Tune function I could compensate to get it to focus correctly at 400mm, but that introduced severe front focus issues from 120-250mm. Overall, I could get the 150-300mm range to focus well if I gave up on the 120mm and 400mm ends.
