...this is what I took along with me on the moto to shoot the USA Pro Cycling Challenge in Colorado last August. Kit has changed a bit since with the 70-200 upgraded to a mark II, 2.8 fe replaced by the 8-15 f/4, and the 1D3 has been sold to raise cash for the pending 1DX... Think I used all the gear except for the 100-400... or the TCs, come to think of it.
1D4, 5D2 gripped, 1D3, 300 2.8L IS, 100-400 4.5-5.6L IS, 70-200 2.8L IS, 24-105 4L IS, 17-40 4L, 15 2.8 fe, LB 3G, 580exII, 420?EX, Quantum battery, ContourHD GPS, all stuffed in a chest vest (well the 300 2.8 lived in the saddle bag of the moto).
Had a lot of fun with the contour hd cam, and did get a shot or two with the lensbaby, but nothing from the moto.
