I use the Canon 5d and Canon 40d with the Canon 24-105mm lens, Sigma 17-35mm., Canon 100-400mm lens and the Canon 580 flash.Some of the photo's will be taken with the Sony DSC-T100 and Leica D-Lux 3 for moments when i could not whip out my SLR! I am trying to perfect my photography so any comments is most appreciated.Thank you for your interest!
