I have read a lot of rave review about the 20D and I am considering should I make the plunge into the digital world. I am currently shooting film, and still a die hard on analogue. I have seen a lot of progress made by DSLR, espcially from the reviews I read on the 20D, but I am also skeptical about the fast pace of changes in this format. For ex&le, the 10D was replaced by the 20D in only a short span of time and thast keeps me wondering when they are going to replace the 20D, maybe end of this year? This is the fear I had that kind of put me back from making the switch. I was just wondering if any of you guys out that who make the switch ever felt like you are constantly trying to keep pace with the replacement. To me, that's a lot of money to keep up with newer models once every year. Unlike analogue cameras, they are only replaced once every 4-5 years or longer. Care to convince me to make the switch? Appreciate any input. Thanks.
