The latest generation of the entry-level Olympus E-M10 now includes a 4/3" 20 MP live MOS sensor (previously 16MP), which is said to be the same as in the higher-end Olympus models. It is paired here with the TruePic Vlll processor, and we already had a movable mount for integrated 5-axis image stabilization.
Beyond that, little has changed, especially in the video field. Filming is still done in max. 4K/UHD up to 30fps, of course in 8bit and also without more ambitious features like LOG recording and so on.
At least in the photo mode, the autofocus has been improved, the C-AF should now allow continuous focusing on moving subjects, Face Priority/Eye Priority AF should also focus on faces in profile or looking down. New features include the ability to flip the display down completely for those who want to take pictures of themselves, and the option to charge the battery via USB in the camera. In addition, the camera has become a bit lighter, the housing now weighs 383g.
The Olympus E-M10 Mark IV will be available for 699 EUR (body-only) from mid-August, in a kit with the M.Zuiko Digital ED 14-42mm F3.5-5.6 EZ it costs 849 EUR.
