The Pentax 645Z is a professional medium format digital SLR camera announced by Ricoh on April 15, 2014. While it shares its sensor with the Phase IQ250 and Hasselblad H5Dc, it retails at less than a third of the price of these (~8500 at ~27000 USD).^[1] In 2015, the 645Z won the TIPA Award for the Best Medium Format Camera.^[2]

The most notable improvements over its predecessor, the Pentax 645D, include much lower noise at high ISO, the ability to record video (FullHD at 30 frames per second), and a tilting rear display.

Furthermore, the 645Z is compatible with the Pentax FluCard to allow wireless "tethered" operation.^[3]
