Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Canon Digital SLR Cameras Reviews

Summary: I am Impressed
Comment: I have only just received this lens so I will be giving you my first impressions. I will follow up in a couple of weeks with an in depth review.

First impression is BIG. The lens is big, physically, and it's a WIDE view after using my Canon 18-55mm. It feels solid, well built with everything moving very smoothly and no noise. It locks on to my Canon 300D and 400D XTi solidly with no slop and responds to all commands, AF, Av, Tv, etc.

I have taken half a dozen shots and they have all been clear and sharp without enlarging or in depth investigation. Distortion is typical of what you would expect in this focal length, exaggerating all the mid range distortions. I did manage to get some very respectable non-distorted images by carefully controlling the angles of the POV.

The last observation is that it looks good. I mean it's dressed up a little with the gold band and ribbing.

I am very happy with this lens so far. I will update this review after I play with it a little more in depth.

Summary: Solid, but Fuzzy
Comment: I have taken nearly one thousand pictures with this camera, anything from architecture to nature. While my initial assessment of the camera was good, after having it for some time, I feel that the fuzziness of the pictures is unacceptable. I guess I felt as though it was my initial settings, or maybe becuase of the wide angle of the lens this was something that was par for the course. I have since read about softness on right or left side with this leans, but my experience is clarity is no good accross the entire frame, in EVERY situation. I will either send back for repair or get rid of it for the cannon 10-22 lens.

Summary: Better sharpness, brightness and color saturation than Canon's 10-22
Comment: I just did some test shots comparing the Sigma 10-20mm and the Canon 10-22mm. The Sigma beat the Canon hands down on sharpness, brightness and color saturation without question. I've owned the Canon 10-22mm for almost a year and have never been satisfied with the softness of the images it produces. I've even sent it to the factory 3 times for adjustment. The tests I did today show the Sigma to be surprisingly the better lens hands down. It may be that I purchased a bad Canon lens, but after 3 trips to the factory for adjustment, I would think it would have been spotted. I'm constantly being told by reps how good the Canon 10-22mm is as it has the super UD glass and is supposed to be similar to L series quality. I've never seen this on my 40D and I'm now ecstatic to have found the Sigma to replace it. This is a great lens for a very nice price.

Summary: bad......bad sharpness.......
Comment: I used this lens for 1 week and took over a 200 photos in various shutter speed/aperture combinations; all of them turned out so-so to no good. The center sharpness is ok, but the sharpness and distortion of the image becomes unacceptable, starting about half-way to the image edge.

I don't believe I received a bad copy of this lens as a previous reviewer had as I didn't find one side of the image to be better or worse than the other and the autofocus seemed to be on target.

Summary: SAVE SOME CASH
Comment: SAVE A FEW HUNDRED DOLLARS, GET THIS INSTEAD OF THE 10-22 BY CANON, CANON IS THE BETTER OF THE TWO, BUT, NOT FOR THE MONEY, IF YOU HAVE LENS FEVER! THANKS, SIGMA.
