The camera rocks on the Venue 8. With Lytro comparisons.

What's special about the camera? To be accurate, there are four cameras on the Venue 8; there's one on the front for selfies or video calling, and three on the back. The setup on the rear is the RealSense Snapshot system, and it captures depth information alongside the main image. That means that, as with the Lytro lightfield system, it's possible to change the focus of an image after it's been captured.
RealSense isn't quite the same as Lytro, though. The latter has multiple micro-lenses and captures a lot more information. RealSense uses the extra sensors to capture layers of an image, with the additional cameras providing depth information, up to around 30 metres.
The gallery software provided lets you change the focus by tapping, and a slider controls the bokeh effect. It can look pretty dramatic, but it can also, at times, make the layers very visible. On some shots of the garden, for instance, the end result made it look as if bushes were really just painted flat boards. It certainly can lift photos dramatically, but it's a tool to be used with care.
