I use Canon equipment and all of the photographs taken prior to June 2011 were taken either with an EOS20D or EOS40D. In June 2011 I took delivery of an EOS7D, which took a bit of choosing. It was either a 7D or a 5DMk2, which has a full frame sensor, but the 7D won out on the basis that it has a better focusing system for wildlife work and is proving to be a significant improvement over the 40D for landscapes.
I have four Canon lenses; a 100 f2.8 Macro, a 10-22 wide angle zoom, a 24-105L zoom and a 100-400L zoom. The lenses have recently been supplemented by the addition a a Canon 1.4x Extender.
I also recently acquired a set of Hitech grey graduate filters and a 10-stop ND filter, all to help me with my landscape work.
Other essentials are a manfrotto tripod and a cable release, which go everywhere with me, as does my 12" mini reflector - ideal for macro work, particularly flowers and plants.
Flash equipment includes a Metz Mecablitz 58-AF2 and a Canon 430 EX.
I also have a Canon G7 compact as a go-everywhere camera.
All of my work is taken in RAW and initially processed using Canon's own Digital Photo Professional software. The images are then converted to tiff and finally processed using photoshop. I occasionally use photomatix pro for HDR images, but I prefer manual blending most of the time.
If you have any queries drop me a line and I'll do my best to answer them.
