User Ratings and Reviews

2 Stars save to buy a canon lens
Got this lens as a birthday gift, but sadly had to return it as it did not meet my expectations. The zoom range is great (10-20mm), but I either received a bad copy or Sigma does not offer good quality. I shot about 50-60 exposures, and I can count on one hand the number of good pictures I got from this lens. It was slow to focus, it lacked sharpness. For indoor photos this lens will leave you very disappointed. For outdoor photos, you will need great lighting and non-moving subjects.

The positives: Solid built.

5 Stars Outstanding lens
My first Sigma lens. Usually use Canon L lenses. I have had this for almost a year.The Sigma 10-20 is tack sharp. Something in the lens coating and/or glass really enhances sky/cloud contrast and color, making it look like a polarizing filter was used.

The overall lens quality is excellent and I have no complaints.

4 Stars Very pleased
This is an eceptional lens considering the price. If you are a perfectionist and want to do all sorts of lens test, this is not for you. But, if you are into photography and wand exceptional images this lens will work just fine and produce incredible images at a budget price. You can spend more that twice as much and get Nikon’s latest offering or spend more and get Sigma’s latest offering, but this lens will produce wonderful images!!!

4 Stars I could not find the Canon lense….. but WOW!
I was looking for the Canon lense that a professional photographer recommended. I stumbled on the Sigma lense and love it. The price was right, and the colors are amazing. I don’t think you can go wrong with this lense. I have been a sigma user before as I was building my camera bag and I just wanted a wide lense to get cool landscape pictures. This was the one.

5 Stars Great Lense, Solved My Problem
I’m not a technical photographer. Just a photo hobbiest. As a realtor I knew that I needed to solve the problem of taking interior pictures for listings and not getting enough of small rooms in my pictures. I purchased this lense and it solved that problem 100%.

I’m getting compliments on my listing pictures and find that I’m using this lense most of the time. It takes wonderful, clear, color intense pictures with an almost 180 degree field of vision.

It performs as advertised with no learning curve. It went from the box to my Canon Rebel. I took a few practice shots for lighting purposes, took it to my next listings and shot good photos with no issues.
