I shoot full frame (5DM2) and am contemplating a fast wide angle lens to go with my 85mm F1.8.
I have read good things about the Sigma 24mm and like the extra 4mm.
Does anyone have experience with both?
My zooms cover from 17mm to 200mm at F2.8 so this is really a low light lens when I want to have wide on one body and long on the other. Kind of reminiscent of having my two M4s with wide and long with pushed Tri-X.
