You are quite right, i was being vague and my post lacked details, my bad. And i did appreciate your input.
I do shoot a full-frame D700 and already own the 24-80 and 70-200 VRII, so the 17-55mm DX won\'t cut it either.
I shoot pretty much anything and i realize now that i will try my hardest to find another 17-35mm because althought it could get replaces easily by the assurance company for the 12-24, the latter does not really have the same purpose, unless someone here made the switch and can give me some impression.
