Ricoh officially launched the new GXR A12 M-mount module. You can see a very first preview at DPreview (Click here). As you know it has a 12 Megapixel APS-C sensor. To bad, would have loved to see a fullframe sensor on it. The Ricoh GXR A12 will be available in September, priced at $649. A very intruiging feature is the electronic shutter option that works from 1/8000th to 1 second. It makes the camea extremely silent! And you can create your own user-defined distortion, vignetting and corner color correction, recordable for multiple lenses.
