Excerpt: I bought this lens with hope to avoid heavy spending on the Nikon 24-70mm lens. Got the lens as promised fast and safe. I wanted to try the lens and tried to photography my baby. Outcomes: colors are very nice with good contrast. The problem I had was with the focus and the zoom ring. First, and the reason I returned the lens, the focus point was off by about an inch to from target.
Excerpt: I've had this lens since it was introduced. Have used it on Konica-Minolta 7D, Sony A700, and Sony A99V. It was excellent lens on both 7D and A700 but have noticed considerable back focus on A99 @ F2.8/75mm. It gets progressively sharper as F stop larger (4.0-8.0). At 8.0 lens is really sharp. To be fair this typical for most lenses. I did AF Micro Adj on A99V and that so far has seemed to fix front focusing.
Excerpt: does not have an easy fit onto the nikon D600, used it at an indoor event and is provided good range for group shots and individual photos. On a large group shot indoors at 2.8 there was some distortion in the people on the edges.
Pros: Fast / accurate auto-focus, Lightweight, Nice Bokeh
Ok lens if you're willing to settle for mediocrity

Summary: I expected better image quality from this lens. To say that I am disappointed would be an understatement. I own other Tamron lenses that far exceed the optical qualities of this lens. When I wrote to the Seller and requested an extension of time to return the lens the Seller wrote back implying that it was probably a problem with my camera.
Excerpt: You can visibly see the corners of the lens hood when between 28-55mm with a full-frame D800. I just sent Tamron an email about this, wondering if they have an alternative hood. It is an excellent lens and the value is amazing compared to Nikkor lens costs, but I personally like to have the lens hood on while shooting, this issue means I can't use the hood.
Excerpt: This lens would be good for a travel lens on a full frame camera, but I would not recommend it for professional use unless you are absolutely, positively certain that your copy works at all focal lengths. I've had two copies of this lens, and I've wound up reselling both of them. It's not a bad lens, with sometimes truly excellent sharpness and great colors, but the AF is too inconsistent, especially in low light.
Pros: Durable, Easily Interchangeable, Nice Bokeh, Strong Construction
