Previously I was using E510..
Its quite a value for money dslr.
But recently, I've been thinking of upgrading to another newer dslr.. either nikon or canon or olympus...
From what I know
Olympus has the best dust cleaning body system but its at bottom on ISO performance
Nikon in the middle for cleaning system, but is good at ISO performance
Canon at bottom for cleaning system, but is best at ISO performance (from what I know)
Pls advise on which model I should keep a look out for.
Btw, most of the time I'm shooting human portraits (some times will need to shoot from far to close up in performance stage...) and some times landscape also
