Customer SLR Camera Lens Reviews

Great lens for a reasonable price,

I’m using this wide lens with a Canon Rebel XTi. There are many things to like about this lens: a) its ideal focal range for inside and outside shots. It is ideal for walk-arounds, b) the IQ is very sharp, in fact I find little difference between it and mt Canon 50mm f/1.4 fixed lens, c) other IQ features the 70mm lens capabilty is cool — you can get about an inch away from an object and still get a sharp focus,and best of all e) the price is reasonable. One negative is that compared to the Canon lenses, it doesn’t focus well in low light; you may need to manual focus in some cases. Another very small negative is that it is slightly heavier than my other lenses and feels a little unbalanced on my XTi but this is almost not worth mentioning. Of my 5 lenses, (4 are Canon’s) I would grab this first if I could take only one with me. I highly recommend this sigma 17 70mm lens.

I really like this lens sigma,

I have been searching for a better walk around lens for my Canon Rebel XTi since the Kit lens is just to soft and suffers from chromatic aberration. I had been thinking about and have tested a Canon 17-40L in the store and borrowed a friends Canon 24-70mm f/2.8L at the zoo and thought they were both pretty sharp lens. My friend recently purchased a Sigma 17-70mm F2.8-F4.5 Macro DC lens and asked if I wanted to try it.

Imagine my shock when I got this sigma macro lens home and it blew away not only the and Canon 24-70mm but also my Canon 70-200 2.8L in sharpness!!! My new Canon 17-40 F4 L is sharper though This lens is so tack sharp you had better wear gloves when you handle it!! The images were razor sharp edge to edge at all apertures.
This sharpness is great for landscapes cityscapes, macro shots etc but a little too sharp for portrait as every little blemish is shown!

And the flash problem I was having with my Rebel XTi was all kit lens. This sigma 17 70mm lens using indoor flash just plain rocks with even lighting edge to edge using my Canon 430EX Speedlite even at 17mm and no sign of chromatic aberration I was having. Just one warning for those without external flash the lens hood will cast a shadow on the bottom of your photos if you are using the built in flash.

Another surprise was the auto focus which has to be the fastest non USM auto focus I have ever used. It won’t quite keep up with my Canon 70-200 2.8L but it was close. I had my daughter run towards me with the lens at 70mm zoom from 40 feet away and got 5 good focus shots in sports mode with the Sigma and 8 good focus with the Canon.
