I have purchased two of these lenses (autofocus version) for our Nikon N-70. I dropped the first lens and something came loose. This is a superb lens. I studied the Modern Photography Magazine ratings to select this lens, which was/is the sharpest zoom lens in the 20-120 range. Not even Nikon or Canon can beat this lens for sharpness across the focal range. Spherical Aberration is marginally higher than an average lens with this focal range, so you wouldn't want to shoot professional architecture photos with this lens. Tamron makes a semi-pro lens with an F-2.8 across a similar zoom range, but it is no sharper than this lens.

I have used this lens with my Rebel 2000 and EOS-3. It's an excellent lens! The auto focus is fast and relatively quiet, the image quality is excellent. The best feature in my opinion is the large lens area, it captures lots of light. This is an A+ lens for the price.

I shot my first wedding using this lense, it performed outstanding. I am very satisfied and will continue using this lense with my Nikon D70s camera.

Great addition to my Sony Alpha a100. Yes thats right it works with out a glitch with my sony. It takes awsome pictures and goes the extra distance that the standard lens that comes with the a100 can not simply do.

I needed to replace my Sigma 55-80mm lens for every day use and the Tamron was recommended to me as potential replacement. Based on the price and 6 year warranty, it has exceeded my expectations.
