The competition
The E-620 is relatively expensive at present, although its price is likely to drop in the coming months.
Its current price puts it alongside the Nikon D90 and Canon EOS 40D, and in terms of specification it can compete with both.
The Nikon D90 offers a superior phase-detection AF system and a video recording mode, but it does not offer the same level of sophistication in its Live View mode.
The Canon EOS 40D contains less advanced technology than either camera, but offers significantly better build quality than both, albeit in a larger, heavier body.
A first-time DSLR buyer would be well advised to go for the E-620, but a more experienced photographer would probably get more out of the D90.
Anyone currently using an E-410 or E-420 who is considering an upgrade should consider the E-620 over the more expensive E-30, given the similarity in performance.
