Let’s talk about the specification comparison between the Sony A6400 camera and the Olympus E-M5 III camera. ow before we begin let me tell you that we ony do carry a large sensor inside it. If, you are someone who mainly shoots still images only. Then without moving into details my suggestion is you should buy the Sony A6400 with IMX 271 APS-C Exmor CMOS sensor.
With the Sony 24 MP sensor you will be getting more more bit depth, more dynamic range, better color output and more clean low-light images when paired with bright aperture lenses.

Sensor Image stabilization missing inside Sony A6400
The selling point of Olympus apart from DCI 4k is built-in image stabilization. The camera features 5.5 Stops of butil-in image stabilization system which can be further enhanced upto 6.5 stops when paired with the OSS lenses. With Sony you have to depend upon broad ISO range and OSS lenses for getting clear shots at night.
Large Sensor area and better ISO range in Sony A6400
The ISO range of the Sony A6400 camera is more than of the new Olympus E-M5 Mark III camera. The expandable ISO range of Sony is 2 stops more than of the Oly. More or less we are also getting larger sensor are with Sony APS-C sensor. So, be assured you will get better low-light performance with the Sony A6400.

DCI vs UHD Despite of having a smaller sensor the camera is able to grab out DCI 4k videos whereas the Sony A6400 camera records slightly lower resolution UHD 4K videos from a large APS-C sensor.
Limit vs No-Limit: Sony offers unlimited video recording option. with Olympus we do have the traditional 30min video recording limit. So, of course Sony is bit better for longer run.
