Will.i.am foto.sosho V.4

LAS VEGAS--The foto.sosho V.4 is an iPhone 4S case that gives you a shutter release, flash, and the ability to attach one of three lenses: standard, fish-eye, and wide-angle.

The case is fairly thick, so it's probably not something you'll want to keep on all the time.

On the other hand, the thickness is because the whole front slides down to reveal a Bluetooth keyboard. The Bluetooth also allows you to use the case's flash off camera for helping with things like harsh shadows in portraits.

The C.4 is basically the V.4 without the Bluetooth keyboard. You still get lenses and the built-in flash and shutter release, all for the low, low price of £199, or about $319.

A third version, the V.5, is actually more of a full camera, with a 14-megapixel sensor, imaging processor, a 5x zoom lens, and built-in flash. The iPhone will power the camera's functions and, of course, give you access to apps for editing and sharing.
