Average Reviews:
(More customer reviews)This Tamron is a very well made, sharp above F4, a little heavy compared to today's zooms, but the results are great. I shoot a lot of cars, and the distortion is controlled very well. The only real negative that I have found so far is the lens has a lot of flare. You really should use the lens shade on this one. The one I received is the re designed version of the one pictured. I wish they would get the picture right. I really wanted the version pictured. For an older lens, it works very well with the digital camera's. I have tried it on the D70 and the D90 with no problems. Highly recommended.

This fast ultra-wide angle zoom is a logical option as a standard lens with its 40mm focal length. Thanks to a large 42.5mm diameter compound aspherical element in the front group, and another aspherical element in the rear group, distortion and chromatic aberrations at the wide angle setting are eliminated. Use of a polarizing filter is possible thanks to the internal focusing system and large 77mm filter diameter. A flower-shape bayonet-type lens hood is supplied as a standard accessory.
