Canon EF 8-15 L lens or Canon EF-S 10-22 for landscape shots (mountains)

Thanks everyone, as usual your insights are quite useful.  I will stay away from the 8-15 because I don't like the distortion and will look closer at the Tokina and Canon with my preference being towards the Canon at this point which is surprising me.

I'll also look at the Sigma 8-? as one member suggested but I suspect it will also be fisheye.

DxOMark also has a lot of great info on lenses which has been useful.  It allows you to search against criteria to find various lenses for review across manufacturers according to mount type, etc.

Thanks again,

Trevor.
