"Disappointed with performance"2.0 starson by KellieHam
Pros: Small, portable, easy to use
Cons: Many unsharp, lo-res looking photos
Summary: I have a Canon 800 IS I love, It was getting worn and I wanted to try to f2.0 with the 400IS. I was pretty excited--I've won photo contests with greatly enlarged photos from my 800--it's that sharp. So many of the photos printed at normal size (5x7, 8x10) from the 4000IS are grainy, I really don't enjoy using it.
