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

The Sigma 70-200mm F2.8 EX DG OS HSM is a bold attempt to challenge the quality and functionality of some of the very best lenses on offer today - the fast image-stabilized telezooms from Nikon and Canon.

Very sharp across the frame when stopped down; Minimal color fringing/chromatic aberration of any description; Fast; silent; accurate autofocus with manual override; Very effective image stabilization; Decent build quality; Clever design tripod mount which is quick and easy to remove with the lens...

Somewhat soft and low in contrast at F2.8 towards the edges; especially on full frame cameras; Can give somewhat harsh rendition of out-of-focus backgrounds at longer focus distances; No focus limiter switch; No weathersealing; Susceptible to flare with direct light sources in or close to the frame,...

I debated for a while on whether to wait until I could afford the Nikon version or going ahead and getting the Sigma. I have a trip coming up to Alaska so decided to go ahead and give the Sigma a try. I have only had it for a short while but so far I am very pleased with the results from this lens.

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

Sigma's 70-200mm f/2.8 EX DG MACRO HSM is solidly built and well designed, although the zoom ring could do with being about an inch further forward to make it truly comfortable to use.

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.
