Ricoh Imaging Co Ltd announced the "Pentax 645Z" medium format digital SLR (single-lens reflex) camera equipped with a large-size 51.4-Mpixel CMOS image sensor April 15, 2014.
The new camera was developed based on the Pentax 645D, which was launched in 2010. The largest difference between the 645Z and 645D is their image sensor. While the 645D has a 44 x 33mm 40-Mpixel CCD sensor, the 645Z comes with a 43.8 x 32.8mm 51.4-Mpixel CMOS image sensor.
Ricoh Imaging will release the new camera at the end of June 2014 with a monthly production rate of 400 units. Though there is no manufacturer's suggested retail price, the expected price of the camera is about ¥800,000 (approx US$7,860).
