That is a big investment, Steve, but it sounds like it was worth it to you. As the owner of one of the smaller format Canon DSLRs, I've often wondered it the full format would make enough difference for the kind of photography I do. These days, most of my work is fairly low resolution, for the web, so I decided I don't really need the finer resolution and greater detail of the full format cameras. If I routinely had photos printed at large sizes, I can see that it would make a difference. What do you think of this rationale?
