I still can't decide whether I should get myself the 10-22mm EFS or the 17-40mm... for Christmas.
My photography plans for the future are to have the 5D, 17-40, 50 f/1.4, 85 f/1.8, 70-200 f/4 hence getting the 17-40 would bring me closer.
I'd enjoy the solid build of the 17-40 compared to the 10-22, the L quality, and the fact that I won't have to worry about selling it when I go full frame (2 years). My main concern is whether 17mm would be wide enough on the 1.6 crop for landscapes, equivilant FOV 27mm compared to 16mm.
However I do like the fact that I will have the 30mm focal range covered and hence I can use it as a general walk around - I fear the 22mm would still be too wide.
So my concern, is 17mm wide enough? Will I lose out through the reselling of 10-22?
Thanks
