5.0 out of 5 stars OUTSTANDING, FAST ALL-PURPOSE LENS AT A GREAT PRICE, June 8, 2006

This review is from: Sigma 28-70mm f/2.8 EX DG IF Aspherical Lens for Canon SLR Cameras (Electronics)

This is an excellent lens. I have used it extensively on the 1D, Rebel XT, and the 20D. The lens is acceptably sharp for many purposes at f/2.8, and EXTREMELY SHARP stopped down a bit to f/3.5 or f/4.0, at all focal lengths. I have compared it to the Canon 85mm f/1.8, the 50mm f/1.8, and the 35mm f/2.0, all renowned lenses. I find this lens very competitive with - and in some instances, superior to - all of them in sharpness, contrast, and color. Focusing is fast enough for most action purposes, impressive for a non-USM lens.

I also compared this lens to my Canon 28-135mm USM Image Stabilizer lens. I found the Sigma 28-70 f/2.8 to be significantly superior in image quality. I sold the 28-135 IS. This Sigma is virtually always on one of my digital SLR's.

A significant note - INFORMATION AND PICS I HAVE SEEN INDICATE THAT THIS LENS IS SUPERIOR IN IMAGE QUALITY TO THE MORE EXPENSIVE SIGMA 24-70MM F/2.8. I WOULD RECOMMEND SAVING SOME MONEY, GETTING THE CHEAPER LENS, AND GETTING BETTER PICTURES OUT OF IT.

I HAVE USED A LOT OF SIGMA AND CANON LENSES ON MY DIGITAL SLR'S, AND THIS IS ONE OF THE BEST, BAR NONE.

5.0 out of 5 stars OUTSTANDING LENS At A Very Affordable Price, June 27, 2007

This review is from: Sigma 28-70mm f/2.8 EX DG IF Aspherical Lens for Canon SLR Cameras (Electronics)

This lens is an amazing piece of glass at a remarkably affordable price. While I will readily admit a preference for Canon's signature lenses, especially the IS line, this lens is very tack sharp and shows little or no blur with small jitters. For a closer range lens this is a perfect economical choice for those who want to take better portraits.

This review is from: Sigma 28-70mm f/2.8 EX DG IF Aspherical Lens for Canon SLR Cameras (Electronics)

This lens is a little heavy on the xti (compared to the 35mm and 50mm primes I normally shoot with). It feels very well made and can focus very close. I think it is a great lens for the money and it performs well.
