Wouldn't it be interesting if Pentax did something outside the box like introduce the k-3 as a bridge camera to FF using and APS-H equivalent sensor with about a 1.3 crop factor. The image circles on the DA limited lenses would likely be large enough to serve this sensor with minimal vignetting so users of current pentax APS-C would have an easy upgrade path, the depth-of-field properties would approach that of FF, and maintenance of a compact side would be easier. Such a camera would be truly unique with advantages of size cost and lens compatibility of APS-C, and image quality, DoF, SNR approaching FF; perhaps 24MP?
