So I am pondering a lens switch up as follows...
-sell my 10-22 and buy (or trade for) a 17-40mm
-Sell my sigma 50mm, not really using it
-sell both the 50mm and 10-22 and buy a 35L
now that I have the 5D Im using that more than the 40D and want both a new wide for landscape and a new fast prime.
What do you think?
