Sigma 17-35mm f/2.8-4 EX DG Aspherical HSM review by lucasbutchart

Summary: Wanted to share some love on this lens. It's similar to other newer plastic Sigma zooms: well made, inexpensive, fast focusing, 77mm filters, very versatile zoom range on full frame, full time manual focusing, focus scale, big zoom and focus rings, flare resistant, decently sharp wide open, nice f2.8 aperture for low light, silent HSM, very good minimum focus distance, and probably more.
Sigma 17-35mm f/2.8-4 EX DG Aspherical HSM review by JimCee
19 February 2013
Summary: I purchased this lens in September 2007 in a Nikon lens mount version from Amazon. I've used the lens extensively with APS-C cameras (Nikon D90 and D7000) and it performs admirably! DxOMark recently tested the lens and compared it with a much more expensive Canon EF 16-35mm f/2.8 II USM lens (which costs $1,549.00 at Amazon). The Sigma lens performed very well in the comparison and held its own.
Summary: This lens is a great replacement for most typical 18-35mm kit lenses. Provides a wider angle of view at 17mm which provides more dramatic looking photos. The lens also offers a aperture of 2.8 compared to 3.5 which makes this lens able to shoot in darker settings without having to sacrifice shutter speed or noise from ISO.
Summary: I purchased this lens before for the Pentax K20d and thought it took decent pictures. Just recently upgraded to the Canon EOS 7d and decided to buy this lens for my second body. This was probably the best decision I have made. Not only does the lens focus better but the photos are phenomenal. I've read the other views and don't agree with any of the negative issues people have commented on regarding this being too soft wide open.
Pros: I like this lens, contrasty, color and focus spot on and sharp, sharp,sharp at all apertures. In fact, sharper and better tham my 17-40L GASP...
Cons: Size, a little chunky and limited range, but supurb quality photos, not sure why this is not ranked higher unless I lucked out and got an exceptional copy... Best $240 I ever spent... Make sure you look at the DG version as there are 2 versions of this lens.
Conclusion: I just wanted say after reading the reviews from the past people, they are old reviews and mostly Canon camera mounts, I have used this lenses on my past D100 up thru my D700 and the only reason I selling it now is that I broke down and bought a 14-24 and want to buy the 24-70. The newer Canons focus much better now you should this a try if you get a chance it can be a good bargain in disguise for like was for me.
Pros: Lenses is bright and produces good contrast sharp but for the far corner on full frame. As
Cons: Color is shifted a little from what a Nikon lenses produces, Greens seems more pronounced.
