Pentax 645Z brings video, lower price to medium-format cameras

Building on the success of the medium-format Pentax 645D digital and Pentax 645 film cameras, Ricoh announced today the Pentax 645Z, taking on Hasselblad and Phase One at a fraction of the cost.

The 645Z uses a 44x33-millimeter sensor like its predecessor, but switches from CCD to CMOS. The resolution increases as well, from 40 megapixels to 51 megapixels. It'll capture 14-bit raw in PEF or DNG formats in addition to TIFF and JPEG.

With the sensor change, the camera also gets a speed bump allowing you to shoot at up to 3 frames per second (up from 1.1fps) with a maximum shutter speed of 1/4,000 of a second. Along with that, the Pentax 645Z is the first in the category to offer full HD video capture at 24p, 25p, 30p, 50i, or 60i frame-rates in MPEG-4 AVC/H.264 (.MOV).
