645D is the latest digital SLR camera of Pentax. The Pentax 645D is a medium-format digital camera with 40MP along with 44 x 33 CCD sensor, 3-inch screen size 921,000 dot LCD and comes buit-in with an interchangeable lens system. One good thing about medium format digital camera is its ability to produce super high resolution images(large megapixel) and lower noise level.
Pentax 645D is also compatible with existing 645 system lenses and uses dual SD card slots that can be used either as additional storage and also for back-up. It is also durable because this digicam is built out of a magnesium steel alloy and the LCD Panel is built using reinforced glass.
Pentax 645D is certainly an impressive Medium Format Digital Camera. It will be released this May or April in Japan. Expected price is about $9,400.
