The 645Z Medium Format DSLR Camera (Body Only) from Pentax features a 43.8 x 32.8 mm CMOS sensor with 51.4 effective megapixels. The sensor is designed without an anti-aliasing filter to maximize sharpness and details. RAW files can be recorded at 14-bit and saved using either the proprietary PEF format or Adobe's DNG format. An ISO range from 100-204,800 and high S/N ratio provides low noise, low light capability, and the Prime III image processor lends itself to fast image capture with a maximum of 3 fps continuous shooting. The SAFOX II autofocus module utilizes 27 autofocus points including 25 cross-type sensors and 3 AF sensors dedicated for low light focusing. The new Real Time Scene Analysis System features an 86,000 pixel RGB light-metering sensor for enhanced accuracy of exposure, white balance, and auto-focusing. Full HD 1080 60i/30p/24p video capture is supported in the H.264 format with a dedicated button for instant switchover from stills to video. An external microphone jack enables high quality audio recording with manual sound level control and monitoring. An HDMI port outputs HD images to HDTVs and a USB 3.0 jack enables fast image transfer to your computer. Interval recording for time-lapse videos is supported with an output of UHD 4K resolution. A 3.2", 1037k-dot, tilting, air-gapless, LCD monitor enables live view composition and playback viewing from a various angles and a trapezoid-shaped glass prism viewfinder with Kepler telescope-type eyepiece unit provides traditional eye-level composition. The design of the viewfinder also helps to achieve the relatively compact size of this medium format camera. The 645Z is extremely durable with an aluminum alloy chassis, magnesium alloy shell, and 76 specific weather seals to keep out moisture and dust. It is a camera designed for field as well as studio and can operate in temperatures from 14-104°F. The 645Z offers a 43.8 x 32.8 mm 51.4MP CMOS sensor, which is ideal for ultra-high resolution imaging, large printing applications, and cropping flexibility. Compared to a CCD sensor, a CMOS sensor provides higher ISO sensitivity, expanded uses for live view, faster continuous shooting, and improved movie recording capabilities. The new Real Time Scene Analysis System features an 86,000 pixel RGB light-metering sensor and improved algorithms that further enhance accuracy of exposure, white balance, and auto-focusing. The 645Z is compatible with new D FA autofocus lenses as well as older 645 lenses as well as Pentax 67 lenses via an optional adapter.
