Canon 10-22mm VS Sigma 8-16mm

[Kayaker72]

I was debating the same thing in February. I went with the Canon 10-22 for the simple fact that you can mount a filter holder on the front. I was also playing around with 4x6 graduated ND filters at the time and while you could hand hold them in front of the sigma, you could mount the filter holder on the Canon. Since I was using hard edge ND filters more and more rather than soft edges, lining up the hard edge becomes more important, thus I wanted the ability to mount the filter holder. Another advantage is that the Canon is lighter. Since this was intended to be a secondary lens, it is that much less weight in my pack.

I am still occasionally tempted by the 8 mm range of the Sigma, but 10 mm is still awfully wide.

Here's a picture or two:
