Tamron AF 28-75mm f/2.8 SP XR ZL Di LD Aspherical (IF) for Canon

Tamron applies the Di (Digitally Integrated) logo to lenses with optical systems designed to meet the performance characteristics of digital SLR cameras, and this 28-75mm Di autofocus zoom lens is no exception. Boasting revolutionary downsizing XR technology, the lens is among the smallest and lightest models in the history of fast zoom lenses.

In fact, it looks just like an ordinary standard zoom lens, but offers a fast constant maximum aperture that will reshape your photographic horizons. Specific details include a constant maximum aperture of f/2.8, a minimum focusing distance of 13 inches, and a rotation-type zoom. As with all Tamron lenses, the 28-75mm lens carries a six-year warranty.

Tamron AF 28-75mm f/2.8 SP XR ZL Di LD Aspherical (IF) for Canon Review

This lens gives me better overall results than my Canon EF 28-135 kit lens that came with my Canon EOS 40D. I shoot a lot of sporting events, especially basketball and volleyball in not too well lit gymnasiums. The kit lens wasn’t getting the job done. It gave my softer images and since I’m using a high guide number external flash unit, the auto focus was often too slow. Tamron has solved that problem for me with this relatively fast lens and it does a great job. I can even, with a little exposure forethought, produce some pretty good available light shots. I had better success with the inexpensive Canon f/1.8 50mm fixed lens, but since I’m shooting along the baselines under the basket that lens was a bit long. This Tamron has solved the shortcomings of my three Canon lenses. I’m going to go for Tamron’s 70-200mm f/2.8 next for shooting night baseball, football and soccer. Overall I’m very pleased with this Tamron, although the sharpness drops off a tiny bit at 75mm, but it is still usable for the publications that use my work. In summing it up I’d say this lens gives you a lot of bang for the buck.
