Equipment
My clients always ask me what kinds of equipment I use. I'm not really sure why they do that; the camera, after all, is only a tool. The best photographers just use different kinds of cameras as a kind of short-cut to their vision, and to that extent, the camera doesn't matter.
But, and this is a big but, I do believe in taking your wedding seriously, and equipment reliability and quality matters on the day. Some makers of equipment have better lenses too, or special purpose cameras that are more suited to a certain style of photography.
Because I shoot a mix of photojournalism--where you don't even know I'm there, with any luck--and more formal traditional photography, I use a number of different cameras and lenses, some designed to see in the dark and gather more light than your own eyes, even!
I currently shoot with a Leica digital rangefinder, the M8, and a Leica digital SLR, the DMR. Complementing the Leica bodies are various Leica lenses--and I think they are some of the very best lenses in the world. The rangefinders are also very small and discreet; most people don't even know when I'm taking a picture!
I also use a Canon 5d, which is an excellent digital camera, as a backup, and some of Canon's best lenses as well.
Finally, I also shoot BW film, if you want it, with two Leica M film rangefinder cameras: an M3 which is a classic manual camera and its younger brother the M6.
