Review on Tamron Autofocus 28 105Mm 4 5 6 Cameras by Cody Clark

Bought two of these lenses (autofocus version) for our Nikon N-70. I dropped the first lens and something came loose. This is an excellent lens. I checked Modern Photography Magazine's reviews to pick this lens as the sharpest zoom lens in the 20-120 range. Even Nikon or Canon can't beat this lens for sharpness over the entire zoom range. Spherical aberration is slightly higher than the average lens in this range, so you won't want to shoot professional architectural photos with this lens. Tamron makes a semi-professional F2.8 lens in a similar zoom range, but it's no sharper than this lens.
