What's new / key features

New 12.3 Megapixel High Speed Live MOS sensor and TruePix III+ image processor. We'd expect this to be the same sensor as appeared in the E-30. Sensor-shift image stabilization system with a claimed 4 stop advantage (rather than the 5 stops claimed for the E-3).

New Autofocus System. The E-620 gets a greatly upgraded AF system compared to the previous entry-level models. Rather than having three AF points, it has seven, the central five of which are cross-type (sensitive both horizontally and vertically).

The E-620's standard kit lens is the 14-42mm F3.5-5.6, which is capable of imager (contrast detect) autofocus in live view.

New fully articulated screen. 230,000 pixel multi-angle, 2.7” HyperCrystal III LCD (an improvement over the recent E-30) Live View. Similar implementation to other Olympus DSLRs - fairly quick imager (contrast-detect) AF with selected lenses.
Improved viewfinder. 95% coverage and 0.96x magnification (compared to the similar coverage and 0.92x magnification of the E-4X0 and E-5X0 ranges). Wireless Flash. The E-620 allows wireless control of flash units, such as the new Olympus FL-36R and FL-50R, in up to three groups.
New Power Grip HLD-5. Has room for two BLS-1 batteries, for portrait shots or long periods away from the charger. There are a variety of Art Filters, selected from when the mode dial is in the Art/Scn position
