After taking my Canon 500mm out for a test drive the other day I realize that there is no way that I can sell it. So I am going to sell the Nikon stuff that I have acquired to fund a 50D purchase + hopefully replace some of the Canon gear that I sold...
Here is what I have for sale / trade for Canon gear:
I've got a Canon 24-105L and a 100mm f/2.8 macro for Canon for sale... also a 70-200 f/4L, a EOS 40D (less than 2,000 actuations) and a 1Ds MK III, Also a 580EXII and a Sigma DG-500.
possibly interesting in buying/etc. the 60mm macro and maybe the 80-200.
