At the widest point of the lens, the Sony RX100 Mark II offers an equivalent of 28mm. While we perhaps would have liked to see 24mm as the widest option, 28mm still gives plenty of flexibility for capturing a wide angle of view.
Sony's Sweep Panorama tool enables you to move the camera across the scene to capture an ultra-wide angle of view. You lose all control over shutter speed and the like, and you can't apply digital filters, which is a shame.
A number of different Creative Styles are available. They give you more flexibility than shooting with digital filters because they can be shot in raw format. Different styles are available, including Monochrome.
Dynamic Range Optimizer
Sony's Dynamic Range Optimizer works when you have a scene with high contrast to produce a balanced exposure. You can either have the camera choose the level itself, or five different levels of optimisation are available along with turning it off altogether. In this scene you can see the difference the Optimizer makes in the grass in the foreground of the picture.
There are a large range of digital filters available on the Sony RX100 Mark II, but unfortunately you can't shoot in raw format while using them, though you can keep control over manual settings, such as aperture.
