Review Date: Nov 11, 2006 Recommend? yes | Price paid: Not Indicated | Rating: 10 

 
Pros: Very sharp at all apertures through the whole zoom range, even f2.8. Excellent build quality.
Cons:
None.

After 6 months of using this lens on a Canon 5D I am still amazed by this piece of glass. The images it produces are rich in detail at all focal lengths and at all apertures. Contrast is also top rate giving nice punchy images. It handles well and the build quality is excellent. What more could you want?

Pros: Excellent build quality - very sharp from f4-22, good contrast.
Cons:
A little soft at f2.8. 82mm filters.

I've been using this lens for about 6 months now and on a Canon 5D it certainly has impressed me. Build quality is excellent and the definition isn't far behind the Canon L glass. OK it's a little soft at f2.8, but from f4 to f22 the resolution is excellent, with the optimum being f8-11. Contrast is punchy, giving images that look vibrant and detailed. Autofocus is quick and accurate with hardly any hunting. The 82mm filter size is a bit of a pain, but this is a lot of lens for the money so I will forgive Sigma on that one.
