Photographyblog.com had a crack at the e-620 and awarded it their highest certification. A quote from their conclusion:
“It’s one of the cheapest and most full-featured mid-range SLR cameras, with great ease-of use, compact size and light weight, and excellent image quality in good light. This camera certainly lives up to its official billing as “The Olympus E-620: All our knowledge in one”, and is our pick of the current range of Olympus DSLRs.”
