I get asked about equipment a lot. Both by other photographers and guests who are interested in photography. So here's a quick rundown of what I use...
Cameras : Canon 1D MkIV x2 - Canon's brand new flagship photojournalist's camera is fantastic in low light.
Lenses : 24/1.4L, 35/1.4L, 85/1.2L, 17-40/4L, 24-105/4L, 70-200/2.8L
Flash : 550EX x2 (hardly ever used)
I usually carry one camera over each shoulder, with the remaining lenses in a Domke F1X shoulder bag. There's other bits and pieces and backup gear in the car, but this kit lets me stay mobile and not get bogged down with too much "stuff".
I'll go into more detail on all this stuff soon.
