Olympus OM-D E-M5

With an overall DxOMark Score of 71, the Olympus OM-D E-M5 jumps to the head of the pack of micro 4:3 compact hybrids (including the Olympus Pen and the Panasonic Lumix G), riding in 42nd place right behind the Sony NEX-5N in the DxOMark camera sensor score database, smack-dab in the peloton of such cameras of reference as the Fujifilm X100 and Sony SLT-A57.

The Olympus OM-D E-M5’s 16 Mpix LiveMos 16 sensor delivers a Color Depth Score of 22.8 bits on our DxOMark test bench.

With a Dynamic Range Score of 12.3 EV, the Olympus OM-D ranks 36th in our database for this criterion, outperforming its overall DxOMark score. This is simply the highest score ever achieved by a micro 4:3 sensor. As we will see below on the curves comparing the OM-D E-M5 to the Pen and to the Lumix G, the OM-D E-M5’s dynamic range is superior at all sensitivities, but continues to progress in an even more pronounced fashion at low ISO settings.

As for Low-Light sensitivity, the OM-D E-M5’s measured 826 ISO puts it in 40th place, a very good score given the sensitive surface area of its 4:3 sensor, just slightly behind the best APS-C sensors.

Furthermore, the OM-D E-M5 beats the score for the 16 Mpix APS-C CMOS sensor found in the Sony SLT-A55, and is competitive with that of the Canon EOS 60D.
