Olympus released a firmware update for the E-520 and E-420 DSLR cameras. This firmware update is version 1.1. The update improves the brightness level of optical viewfinder AF target points — a relatively minor update, but one that can be quite useful. The update comes after requests from users, who have found the brightness level lacking in some of the more extreme situations to which the E-520 lends itself.
If you have an E-520 or E-420, you’ll need to hook it up to your computer and use the provided installation program to update your camera. More information is available through the Olympus website.
