the Canon EF 100mm f/2.8L IS USM Macro.
EOS 7D / EOS Rebel T1i
My current lenses are
EF 28-135 3.5-5.6 IS
EF 70-300 4-5.6L IS USM
EF 50 1.4
EF-S 17-55 2.8 IS USM
Nikon D2Xs, D700, and D200, with a D70 in the office
I use them all, though the new D700 may make the D2Xs & D200 unnecessary
My kids play sports and I enjoy being the (self-appointed) photographer. The outdoor sports are easy, but the ice hockey is a challenge! I'm in need of greater back-end skills
