My second favorite lens for concert photography. I use the Sigma Art 50-100 mm lens 1.8 for very dark close venues and this lens works great if I am not able to get so close to the stage. With f2.8 it does well in the dark, changing light environment. Quick and sharp focus

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

Versatile, sturdy, and built with high-quality optics, the Sigma APO 70-200mm F2.8 EX DG OS HSM offers a good value, although it's not exactly cheap.

It lacks weather sealing; and the autofocus falls a step short

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

Sigma's first optically stabilised 70-200mm f/2.8 promises much. Gary Wolstenholme takes a look at whether it delivers.

Excellent centre sharpness at most focal lengths and apertures; Very low CA levels; Fast AF; Optical Stabiliser; Decent build quality

Lacklustre resolution performance at 70mm and f/2.8

I buy Nikon lenses. I'm not a lens snob [yes I am] but I want hardware uniformity so that I can't blame the equipment when there's an issue. There's many small things that immediately stand out as negative to me about the Nikon mount version of this sigma lens. 1.

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.

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

Produces great colours and the focus is pretty fast, however can be a little inaccurate or miss read the subject. at 2.8f the background blur is beautiful! I would definitely recommend this as a economical option to the Nikon version with cost double.
