Ricoh is expected to announce a new digital camera tomorrow called the GXR, which features a number of different interchangeable lens components in what it hopes will be a breakthrough in the way cameras work, according to a video posted by mistake by

The camera will come with interchangeable lens compartments that slot into the camera casing, which, looking at the video, appears to be nothing more than a battery and flash housing. 

The move makes it smaller than the current Micro Four Thirds offerings from Olympus and Panasonic, according to journalist Ben Stevens in a video which has since been pulled from YouTube.

Ricoh will start the new system off with two lens/sensor combos 24-72mm F/2.5-4.4 with a 10-megapixel sensor and VGA film capabilities.  

The A12 will come with a 50mm F/2.5 Macro lens, shoot video in HD and come with a 12-megapixel sensor. 

Launching in December, Which says the body will cost £420 while the two 50mm macro £600 and the 24-72mm £300.

Ricoh has declined to comment on the news.

Expect more details, very shortly.
