here, I used a 4 mega pixel canon point and shoot and my bigger files are from a canon1ds. The rock and ice photo camp I went to said shoot fixed focal lenses, better image quality and more blown out of focus goodness. like a 50mm 1.0 fixed or a 90mm 1.2 fast lenses w short depth of field. I use a canon 16-35 l series lens alot Your image is only as good as your glass, they say....
