Installed with a large image sensor with about 51.4 million effective pixels, PENTAX 645Z is a midsize, interchangeable SLR digital camera to produce ultra-high-definition and 3D images. With a dust- / drip-proof magnesium alloy cover and a tempered glass display panel, the body is durable and reliable for amateur photographers to enjoy casual outdoor shooting. A tilted rear LCD monitor for more freedom for live-view or HD movie shooting enables 645Z to expand usage areas.
