Hi there. As founder and sole member of the Canon Inquisition, I was wondering if there were any other options other than a C@n0n 500D for an add-on closeup lens for my 70-200 VR? My 17-35 AFS focuses ultra close but its repro ratio is 1:8.9 (grimace). I can't really afford the 70-180 or 200mm micro nikkors, don't particularly like the 105 very much. I want longer than 60mm in this case though. Any thoughts/suggestions? or should I add another lens to my (growing rapidly) high priority lens list?
