Digital Camera Info did a close inspection of the Pentax 645D camera prototypes which uses a CCD sensor from Kodak, with a 9-micron pitch, and a resolution cautiously pegged at 18 mega pixels. The Pentax 654D will have TTL flash connectivity and would be compatible with smc Pentax 645 lenses. The model is very finely built and sports a host of features. On the camera it self when comes across buttons like playback, “extremeinformation, trash, exposure compensation, AF Mode and a viewfinder.

The Pentax 645D has an exposure of 1/4000 at f/2.8 and according to sources there is maximum shutter speed, which is high for a medium format camera. Also the 654D can hold up to 645 RAW images in memory though this has not been confirmed by Pentax.One come across buttons for spot, center-weighted and multi-zone patterns, and a switch for single or continuous auto focus modes. The mode dials seem to offer Program, Aperture Priority, Shutter Priority, Manual, Bulb and X Sync modes.

Ned Bunnell, Pentax's director of marketing doesn’t not want to give away all the details and calls the camera "important for studio, landscape and fashion photographers.” He continues by saying that the Kodak CCD “will deliver incredible dynamic range and clarity of image that will not be possible with smaller sensors” seems indirectly targeted at the 16 mega pixel Canon EOS 1Ds Mark II.” No word on pricing but it may just be the perfect camera for those who don't want to spend $20,000 on a medium format camera.
