context_page_description: The Pentax 645 is a medium format single-lens reflex system camera manufactured by Pentax. It was introduced in 1984, along with a complementary line of lenses. It captures images nominally 6 cm × 4.5 cm on 120, 220, and 70 mm film, though the actual size of the images is 56 mm × 41.5 mm.
context_section_description: On the 5th of February 2014 Ricoh announced they would exhibit a new model Pentax medium format digital at the CP+ 2014 Camera and Photo Imaging Show, tentatively titled the "645D 2014". Features announced include a "latest, super-high-resolution CMOS image sensor" and a "tilt-type LCD monitor". The camera was expected to be reaching market in Spring 2014. In April 2014 the camera was announced as Pentax 645Z. It was sold out after launch, as demand (1500 orders as of June 2014) exceeded supply (400 cameras per month) because of its relatively low price ($10,000) compared to other medium size cameras ($30,000).  The Pentax 645Z uses a 51.4 megapixel CMOS sensor and a 27-point autofocus system with two SD card slots in a weather sealed body.
