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

Overall it's a very good lens and a good investment. It gives fantastic results when used at f/4 and also gives very good and perfectly usable images at f/2.8 It's only a notch off the Nikon and Canon alternatives. I am very pleased with it and have not regretted buying it one bit.

A bit soft at f/2.8

Great Build Quality, Stabilizer works very effectively with low shutter speeds, has a very heavy and solid feel, silent and fast autofocus; It has very smooth zoom and focus rings; It performs great in low light situations and provides high shutter speeds

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 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

None

I purchase this Sigma 70-200mm lens as a replacement for my Canon 70-200mm lens without stabilize capabilities. WOW, what a amazing lens, on my first day of purchasing it I went out to back country National park area,I guess I can call it my lucky lens.

Sigma has been producing fast tele zoom lenses for hand-held photography since the late 1980s and, although the new 70-200mm f/2.8 APO EX DG OS lens claims to be a second generation model, we estimate it's the sixth in a line that reaches back to the original AF 70-210mm f/2.8, which was designed...

Lens is a little heavy, but better that cheap, light weight plastic. Lens is used mostly for shooting indoor concerts & sporting events and seems to fast focus very well.

Consistent Output; Durable; Easily Interchangeable; Fast / accurate auto-focus; Rugged; Strong Construction

Heavy

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.

High sharpness at low price. The same type of non-third party lenses (official brands) costs twice more, but the results are very, very similar... Recommended 100%!
