The key feature, from the outside at least, is the three-inch screen which can flip through 180°, so can it can be viewed from the front or back of the camera - and it is this that makes it a perfect vlogging camera, as there is no need to get an external monitor. 

Its video credentials are impressive - it can not only shoot 4K video by downsampling from 6K of data from its APS-C 24 megapixel sensor - it also gives you professional editing formats of HLG  and S-Log. There is an HDMI output too, that allows you to record video to an external recorder.

The autofocus system is start of the art - offering Sony's Eye AF which will lock onto your face or that of your subject with not effort, and has over 400 focusing points to give it near complete coverage of the frame.
