Product Description

This Sigma 50-150mm f/2.8 II APO EX DC Zoom Lens is designed exclusively for digital SLR cameras with APS-C size sensors, and its compact, lightweight body provides freedom of movement and versatility.

The minimum focusing distance of 100cm/39.4in. and the high-resolution power layout have improved the strength of the lens in close-up photography. This lens offers a maximum aperture of f/2.8 and its large depth of field offers greater freedom of creative expression.

Four SLD glass elements are used for maximum correction of chromatic aberrations. The super multi-layer lens coating reduces flare and ghosting and ensures sharp images throughout the entire zoom range. The lens design also incorporates an inner focusing and inner zooming system. As the overall length of the lens does not change during focusing and zooming, convenient handling is assured. The HSM (Hyper Sonic Motor) system allows quiet and high-speed auto focusing with full time manual focus override by simply rotating the focusing ring.

5.0 out of 5 stars Great lens for prosumer DSLR, June 23, 2009

This review is from: Sigma APO 50-150mm f/2.8 II EX DC HSM Zoom Lens for Canon Digital SLR Cameras (Electronics)

I use this lens on a Canon 50D and it works flawlessly. Focusing was fast and accurate and the images were outstanding. I also have a Canon EF 70-200 f2.8L IS, which is one of the best lenses money can buy. I use it a lot in studio and more controlled conditions, but the weight makes it very difficult for a long day of tourist-type walking and shooting. I used the Sigma lens extensively on a recent trip to Paris, indoors and out, It was great in the many museums where photos were allowed but only without flash. I highly recommend this lens for anyone who has not moved up to a full frame DSLR.

I bought it over Amazon to match my Canon 40D. Didn't realize the front focus problem is very serious. Now I sent it to Sigma service center for re-calibration.

Other than that, I like it very much: light weight, nice bokeh, and quiet and fast AF.

Sigma sent it back to me today and it is as sharp as it can be. I am very happy now.

2.0 out of 5 stars Poor focus at f2.8, June 21, 2010

This review is from: Sigma APO 50-150mm f/2.8 II EX DC HSM Zoom Lens for Canon Digital SLR Cameras (Electronics)

I did a side-by-side comparison of the lens and my favorite canon lens 24mm-105mm - both on a tripod and handheld. This sigma 50-150 mm performed almost as well as my expensive canon lens at f4.5 to f22. But below f4.0 it did not focus at the correct depth. Of course the reason to buy this lens is for the wide f2.8 light-gathering ability; unfortunately this is where the lens focuses poorly. I am sending it back.
