![]() This is my favourite walk-around lens for standard use, including landscape, cityscape, people, etc. The Tamron 17-50 lens was not out when I chose this lens, so I couldn't compare it at the time ( though I have been very pleased with 2 Tamron lenses when I owned Nikon/Fuji). The Sigma equalled or out-performed the L lens in resolution and flair control (for about 1/3 the price) in the entire zoom range (I have since also purchased a 17-40mm f/4L lens for my 5D, since my results with the 16-35 were so marginal).Ĭonstruction is not overly robust, but more than adequate, roughly equal to the Tamron 28-75 that I previously owned. Sigma seems to have definately tweaked the optics to excell on a smaller chip camera, as I compared this to my friend's Canon 16-35mm f/2.8L series lens (full frame lens). The resolution is very high at all apertures, and even good wide open. I have used it alot on location, but even used it for small studio catalog photography. But I found that the found that the range of the Sigma lens, it's close focus abilities, and it's resolution more than satisfactory. The 100 had focus accuracy issues, and had to be returned. I was originally going to couple it with a 100mm Canon Macro, and the Canon 70-200 f/2.8 IS to round out my begining kit. This was before Canon came out with their 17-55 f/2.8 IS, but if I were buying today, I think I would have a tough time justifying the Canon lens that was 2x the price, poorer close focus range, ~50% heavier, and bigger, just to get Image Stabilization. I wanted a general purpose wedding lens, that could focus in dim situations. I first got the Canon 20D, and thought this would be a great all purpose lens. No 17mm or even 16mm, No IS like the expensive CanonĪs a Pro, this is the first lens that I purchased when I switched from Nikon/Fuji to the Canon system 1.5 years ago. I am happy with it, and having compared a number of shots I have taken with the 17-40L with the same or similar shots taken with this lens, can see no difference at all.Ī very, very good lens at a bargain price It balances beautifully on the Camera and works well with the built in flash, ie no shading. The lens is very sharp indeed, the colour and contrast are excellent, and the edges are fine.Ĭlearly designed to work well with a cropped sensor, Sigma have got this lens right. Having used the lens for a couple of hundred shots, I have to say I am mightily impressed. It has a sensible size and shaped hood too, unlike the bucket like affair the Canon comes with. The lens is smaller and lighter than the Canon without feeling too flimsy. However on the basis of "bring it back if you dont like it" I decided to give it a try.Ī smart move. ![]() I really dont like the Sigma finish on the EX Lenses, it is almost impossible to keep clean, its almost tacky. ![]() I have used the 17-40L Canon lens a lot in the past, and have always thought it is a great lens.Very pricey though, not a lens I would stump up for at new prices.Īt first glance I was not over impressed with the Sigma, as new, in its box for less than half the cost of a new 17-40L. ![]() I always buy seconhand, the savings are huge. I bought this lens from my local camera store to go with an EOS 20D, having decided to go back to Canon. ![]()
