​Sony is using a new 24-70mm equivalent F1.8-2.8 lens, which is both faster and wider than what was on its predecessors, though at the expense of telephoto power. When you combine its fast lens and larger-than-average sensor size, the RX100 III promises stronger low light performance and shallower depth-of-field at the telephoto end than most other enthusiast compacts.

The housing for Sony Cyber-shot RX100 Mark III allows you to capitalize on the camera's full potential and to capture pictures underwater. Easy access to all key/main camera controls by means of clearly labeled laser-engraved long lasting buttons. An easy and quick release camera mounting plate allows the camera positioning; the back door has a large window for a fine camera display view and it is entirely detached from the front body to make easier the camera fitting. Sony Cyber-shot RX100 Mark III own strobe lighting can be used fitting an outside diffuser on the porthole. For better performance with wide-angle lenses, one or two external strobes can be connected by optical fiber using the adaptor included.
