I use Canon equipment - the following is a list of the main camera equipment that I use:-
Canon EOS 1D Mark II N
Canon EOS 30D
Canon EOS 7D
Canon 500mm f4 IS L
Canon 100-400mm f4.5 IS L
Canon 100mm f2.8 macro lens
Canon 24-85 f4.5 lens
Canon 17-40mm lens
Sigma 180mm f5.6 lens
Canon 1.4x and 2x extender
2 Canon 580 EXII flash guns
2 Canon 550 EX flash guns
Canon MR14-EX ring flash
Canon ST-E2 flash transmitter
Several San Disk storage cards
Wimberly tripod head
Manfrotto 55 non carbon tripod
2 Uni-loc tripods
Seculine Twin 1 R3-TRC remote shutter release
When in the field, especially on foreign trips, I use two portable storage devices and back up all images to each device. I have a Vosonic VP6230i and a Vosonic VP6210. Both have proved excellent investments and I have never filled either disk (80 GB and 100GB respectively) even though I shoot in RAW only, and my trips can be anything up to 6 weeks.
