What camera equipment do you use?

My primary camera for most of these photos was a Canon EOS 40D (although I've recently upgraded to a 70D). Because I travel to some extreme places keeping my equipment in top condition is a big problem. I need a robust camera and the self cleaning sensor is a big plus. As standard I use a Canon EF 24-105mm 1:4 L IS USM lens, but when I can take the extra weight I also carry a Canon EF-S 18-55 lens and a Canon EF 70-200mm 1:2.8 L IS USM lens with a Canon EF x2 extender and sometimes a Hama tripod. As bright reflective conditions are the most common for me, my standard and wide angle lenses are fitted with Hoya circular polarising filters and Canon Lens Hoods, the zoom lens is fitted with a Hoya UV filter as standard to maximise shutter speed and minimise shake, because often subjects hide in trees. I shoot solely in Raw on Sandisk Extreme CF cards and process in Photoshop CS2. My lens and body in standard set up weigh nearly a kilo and therefore for the most extreme conditions, where this weight is prohibitive, or extreme temperatures which restrict camera performance I use a Canon Powershot A1100 IS powered by disposable Lithium AA batteries which weighs much less and is functional down to at least -40C. Some photographs on this site have been taken with less powerful cameras such as a Fuji Finepix A340 or Nikkon E8800. The home page purple sunset image was taken with the Nikkon.
