Summary: This camera is out of production but I wanted to leave a review for it since others may use Amazon to research their purchase of an E-620. I had one and found it a mediocre camera for the following reasons: 1) Image quality. All of the photos that I took lacked sharpness. Normally, I would use the jpeg files and the camera's processing is poor. Because of the poor jpeg files I also wrote files out to raw but those were slightly better but also not that great.

Summary: If you're considering buying one of these used, refurbished, on sale, as an upgrade to an older E-system camera, etc. - STOP. I bought one of these as an upgrade to an E-300 (which I should have kept until making a more satisfactory upgade) so that I could continue to use the same Olympus flash and a few other accessories. I thought the upgrade in features while maintaining a compact size for travel/portability was worth it.
Summary: I bought this camera to take photographs for hiking guidebooks. It replaced the Canon Elph cameras that I used to carry. I selected it because it was the lightest Digital SLR in its class. The camera began malfunctioning after 14 months, just after the warranty expired. It still takes pictures normally, but when I press the menu button, the screen fades out. I'm apparently not the only one who has had this problem (search for "E620 display vanish").
Summary: I upgraded to E-620 from E-510 and was a mistake. I returned the camera for a refund. If you're a first time Olympus user you may be satisfied but for 510 users, you will not. E-510 is a very exceptional camera for its class and other classes of Olympus as well. It offers exceptional details and sharpness. The E-620 details are smeared up and has some serious focusing issues, focusing is inconsistent - sometimes sharp other times are not.
