One of the favorite lenses among news photographers, a 70-200mm f/2.8 or 80-200mm f/2.8 zoom also appeals to many serious photo enthusiasts. Although large and heavy, lenses of this type offer several benefits.

I shoot at a semi-pro level. This was a great lens to add to my bag. It did not break the bank like the Canon 70-200 2.8 IS. I have shot with both lenses side by side. I will say the Image Stabilization on the Canon is better just not 2x the price better.

This is the first time I have used a lens of this size, weight and features. So far I am pleased with the ease of which I can test each of the auto, manual focus and stabalizer features. For my style of photography I am pleased with the image clarity and colour.

After reading what feels like dozens of reviews - all complimentary, I decided to take the plunge and get one of these - I do a lot of indoor fast action and kids photos, needed something fast and decent zoom. Unbelievably sharp photos, better than my prime lens...

Easy to use; Build quality

I purchased this lens after a recomentdation. After using it for a day to get familiar with it, I found that it was just too slow for an f2.8 for the money. The focus seemed to be just a little bit off when wide open at 200mm.

Nice Bokeh; Strong Construction

Slow Focus

The Sigma APO 70-200mm F2.8 EX DG OS HSM ($1,259) is a less-expensive professional alternative to similar lenses from Canon, Nikon, and Sony. The stabilized 70-200mm f/2.8 zoom is the go-to lens for many an event shooter, and getting one for under $2,000 is an appealing prospect.

Excellent center sharpness through most of its range; Fixed f/2.8 aperture; Includes tripod collar; Optically stabilized

So-so images at 200mm f/2.8; Distortion at 70mm; Edge performance could be better

Mount: Canon, Nikon, Pentax, Sigma, Sony A Format: Full frame Construction: 22 elements in 17 groups, nine diaphragm blades Closest focus distance: 140cm Filter size: 77mm Autofocus: ultrasonic (ring) Dimensions: 86 x 198mm, 1,430g Tested on: Nikon D7100 Compared with the equivalent Canon and Nikon...

Even though there's a slight drop in sharpness at 200mm, the Sigma delivers excellent overall image quality, making it exceptional value at the price.

Value for money; Overall performance; Dual-mode image stabilizer

Slight loss of sharpness at full zoom; f/2.8 maximum aperture makes it big and heavy

This is a great value-for-money lens. It feels great in the hand, but more importantly it focuses quickly and is very sharp.

Consistent Output; Easily Interchangeable; Quick Focus; Sharp Focus; Strong Construction
