One thing I really love about digi is the possibility of shooting in very low light situations. My camera the Canon 5D Mark ll is an older model but still greatly out performs what I can do with pushed Tri-x. I shot at ASA 2000 several times yesterday. The ability to change ASA as you go, to have auto focus and see what's happening quickly allows for the ultimate in quick photography of people. I still am using the manual on the camera which allows me to control light better but is a bit slower. Another great thing is you do not run out of film at the wrong moments! Something that happened to me several times with the Rollie today.
So far I am having fun with digi camera but still love the look and feel of film much better.
