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.

This is my main glass for sports, since it was my first purchase for shooting HS Sports. I have used it with the Rebel and 40D. This lens is simply great for the price and is great for almost all sports. For the beginner, intermediate or casual shooter, you can not get a better lens for the price.

All you could want from a 70-200 2.8 - period; Sturdy and strong; Just solid; Price

Focus can zoom in and way out when you are in autofocus; Just boom -out of no where; Compared to the Canon 2.8 equivalent (which I borrowed) It is a slight bit off; You will have to work hard to get sharper images

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...

Pictures are sharp just in the midle at f2.8. (but usable) So. All pictures from http://3foto.ro/sedinta-foto-majorat/ were made at F5.6 with nikon D610 and from http://3foto.ro/sedinta-foto-seniors/ were made at f2.8 to 4.

Good for portraits; Good OS; Good colors

Sharp just in the midle at f2.8

It's expensive, but not as expensive as similar lenses from the first-party manufacturers. If you want speed, quality and versatility, the chunky Sigma 70-200mm lens is a belter.

Fast constant maximum aperture; build quality; AF/MF switching

A focus limiter would be nice; no macro ratio scale; no image stabilisation

I wanted a nice F2.8 70-200 lens every since my son was on the wrestling team and the low light of the gym made a lot of my pictures grainy. I did my research and narrowed my choices down to the Canon L series F2.8 70-200 IS II and the Sigma F2.8 70-200 with OS.

Lower cost than Canon lens; 4 year warranty ; awesome pictures

High cost

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.

Since I couldn`t afford Nikon version of 70-200mm, I decided to go with Sigma. I did very extensive research and decided it`s worth the money. It`s been over a month, I took maybe thousand pictures with it. I can say this I`m in love with it. It`s a perfect lens for portrait works.

Price; Bokeh; Sharpness

Smooth at 200mm

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
