I shoot with the 5D Mark II. Awesome body that has HD video functionality which is an awesome perk.
I have a number of lenses but my favorites in no special order to shoot with are:
EF 70 - 200 mm 2.8L IS - heavy but great bokeh
EF 28 - 70 mm 2.8L - macro - works for my close up shots and standard shots
EF 100mm 2.8 - macro
EF 20 - 35 mm 2.8L - wide angle lense
EF 50 mm 1.4
Lensbaby - a fun lens that warps the picture a bit
