Well, this (Canon Eos 20D w/grip) is my first Digital camera of any kind. I have to say that I'm amazed at the flexability that a DSLR gives the photographer. With film I could never change ISO between shots!
Also I'm amazed at the 20D's lowlight preformance. I have shot alot at night (someing I rarely did with Film) and like knowing in camera after the shot how it looks. Also I have never touched up night shots too much once they were downloaded in to my computer. I've printed 8x10 shots a locate power plant that was taken at night and the results are great.
I have taken 2 weddings (both on the same day & both in different towns) ((yes, I was stress)) with my 20D. I love working with the camera, I have 3 gigs of memory (on two card) and a stand alone storage device. I love never having to stop to load film. Just pop a card out and put another in. My assistant puts the photos on the device.
I'm one very happy 20D owner. I've had the camera 3 months and have a total of 5,600 shots!
