I'm looking for opinion as I cannot make up my mind.
I currently own a 7D and a 5d Mk II. I currently own a canon 10 -22mm EFS len for the 7D. This is used for my wide angle landscape work. but will be moving to the 5D Mk II when i get a decent full frame wide lens. My question is this....What are your opinions on the 7D/10-22 combo for image quality and edge to edge sharpness(@ F8 - 16) vs a 5d Mk II and a canon 17-40L, as a stepping stone for moving to full frame/wide angle. I will eventually move to a 16 - 35mm F2.8 but in the mean time for cash reasons and upgrade of filter sizes reason I'm stuck on the question posed. I've done plenty of research on all these items,(photozone, dpreview etc) but i'm after opinions of the real people out there using these combos(or those who just have strong opinions!) is a worth while middle step, or whould i wait?
