A camera shop recommended one of these and I'm quite tempted. It was recommended before they knew I was a traditional Olympus SLR user.
One of the advantages was that it has the vibration reduction within the camera as opposed to in the lens. This means you can use any lens which is compatible with Olympus.
Having said that, my old Olympus fit Zuico lens are not highly recommended in use with the Olympus E-520, although they will work.
I am also looking at Nikon D70, D80 and D90 depending on budget.
Any thoughts on how the Olympus E-520 holds up against these cameras?
