New camera uses 51.4MP CMOS, with peak ISO of 204,800
Today, Ricoh Imaging Americas Corporation has revealed the new Pentax 645Z magnesium alloy-bodied, medium-format DSLR. The new camera features a 51.4-megapixel CMOS image sensor, tiltable LCD, and is the only camera so far in the medium-format category to offer video recording capabilities. The new camera has a shutter speed of up to 1/4000th of a second, and has an top ISO of 204,800.
Additionally, the 645Z is compatible with the recently-introduced FLU Card, providing remote operation of the 645Z -- including the ability to release the shutter, view a live-view, and browse and download the images recorded on the card using a wireless connection to a smartphone, tablet, computer or any web browser-enabled device.
The 645Z incorporates a newly designed SAFOX 11 phase-matching AF module with 27 sensor points, including 25 cross-type sensors. It also detects the light flux of an Æ'2.8 lens to optimize focusing accuracy when using a large-aperture lens. Its AF working range of -3EV to +18EV (at ISO 100; at 23oC) assures focus with dimly illuminated subjects. The camera is also capable of Full HD video recording at 1920x1080 pixels at a 60i frame rate.
The Pentax 645Z will be available for purchase in June at a retail price of $8,500.
