From what I understand this uses an electronic front curtain shutter, which I do not know how does it work.
Does it present the same disadvantages as a regular electronic shutter? - which are:
- banding when there is fluorescent lighting
- rolling shutter / slow scanning on rapidly moving subjects
- less bits for storing color information (this happens in some panasonics when using the electronic shutter, maybe it also applies to other cameras, I do not know.)
