DxO Labs have released their detailed findings on the Olympus E-P3’s new 12-megapixel sensor. The overall DxO Mark Sensor score is 51, which is surprisingly low, given that even the older and cheaper Olympus E-PL2 achieved a somewhat higher rating. The site puts raw dynamic range at 10.1 stops (at base sensitivity), which sounds like a lot but is actually among the lowest values they’ve ever published for a digital camera. The E-P3’s low-light ISO score of 536 is also quite low for a recent interchangeable-lens camera, although higher than that of the Panasonic GF2’s rating of 506. (Remember that these numbers measure raw sensor performance only, and tell you nothing about things like the cameras’ handling, focusing and operational speed, image processing, mechanical quality or overall ease of use.)
