Been using 350 D for more than a year now. So far no major complaints about the performance. It's just eh handling that quite bothers me. Buying the vertical control grip solved the problem a little.
In my opinion, it's not worth upgrading from 350D to 400D. It's just 2Mp more and a bigger LCD. Unless you've got the money to spend. Otherwise, I'll just spend my money on other photography stuff like flashguns, Lens?, filters?, Studio lights... etc.
I'll be upgrading next year to EOS 1 MarkIIN
HOPEFULLY. Its 8.2Mp, just
.2mp more than my current 350D but its built to last and survive which is more important to me than pixels. My main forte is Events/Sports Photography naman so I won't be needing extra pixels. I need speed more than anything else.
Anyway, Canon 400D is a great a camera!
You can never go wrong with this. And yes, I've been using Canon Since 1997! Almost 10years na!:)
