Olympus announced the 12-megapixel E-620 digital SLR this morning. The new E-620 is the second “Creative” digital SLR from Olympus. It’s sort of a combination of the E-520 and the E-30, with the E-520’s size and build and the some of the features and performance from the E-30, including a 12-megapixel sensor, Art Filters, Multi Exposure, improved auto focus and a 2.7-inch tilt-swivel LCD. I think the E-620 is the camera many Olympus photographers were hoping the E-30 would be - a compact, high-performance upgrade to the E-520 platform.
