Average Reviews:
(More customer reviews)I purchased this lens for my Canon Elan IIe in June, 2000. I've run about 50 rolls of print film through the camera with this lens and have been very satisfied with this lens. Please note that if you get the Canon EOS mount, the HSM is "micro-HSM," which like Canon's "micro-USM" does not allow full time manual focus (you must toggle a switch on the lens barrel to go from autofocus to manual focus). Filter size is 82 mm, which is large and increases the price of filters. The up side is that I have had no vignetting with a Hoya HMC skylight filter (normal, not thin width) a very good performance with an ultra wide angle zoom. Minimum focus distance is 0.5 meters (about 19"), slightly longer han one would like. Flare seems well controlled with the included hood and ghosting is minimal when shooting into the sun at f/8-f/16. Lens has very usable depth of field scales for f/11 and f/16. Nice sharp and contrasty results with this lens make it a bargain when compared to some of its competition.

The Sigma 17-35mm f2.8 EX aspherical HSM lens combines a fast f2.8-f4 maximum aperture with an ultra-wide-angle zoom of 17-35mm. Also, by incorporating aspherical lens elements in the front and rear lens groups, it corrects spherical aberration that could distort your images. The internal focusing system prevents the deterioration of optical quality when you are at a close distance to your subject, and it eliminates the rotation of the front barrel during focusing. The AF drive comes equipped with a silent, responsive hypersonic motor that lets you photograph your subjects without disturbing them. This lets you capture amazing wildlife shots without the noise of an ordinary AF lens. The lens materials used in this new lens are lead-free and arsenic-free ecological glass. This model is dedicated to Canon AF SLR cameras.
