This a complete kit consisting of the Pentax 645D medium-format camera and the Pentax-D 55mm f/2.8 SDM AW lens. The Pentax 645D is a high-resolution medium-format camera inspired by the classic Pentax 645 film cameras.

Large Sensor. The 645D is based around a 40MP medium-format (44 × 33mm) CCD sensor. It provides a top resolution of 7,264 × 5,440 pixels, which is ideal for ultra-high resolution imaging, exceptionally large printing applications, and outstanding cropping flexibility.

0.78x Crop Factor. Multiply any compatible lens’s focal length by 0.78 to calculate its 35mm-equivalent focal length.

Advanced Functionality. The 645D has a 77-segment metering system and 11-point AF system for reliable, accurate shooting. With an ISO range of 200-1,000 (expandable to 100-1,600) and highly flexible white-balance options, it’s easy to shoot in less-than-ideal conditions.

High-Quality Build. The camera has a rigid aluminum die-cast chassis covered in magnesium alloy for a heavy-duty yet lightweight body, and is fully weather sealed and coldproof for shooting in any environment. The all-glass, trapezoid pentaprism viewfinder offers a 98% FOV angle for accurate framing applications, and the large 3" 921K rear LCD is great for reviewing images

Other Features. Dual SDHC/XC memory card slots allow for various recording methods (8-bit JPEG, 14-bit RAW-Pentax PEF, or Adobe DNG). It has mirror lockup and dampening features, multiple JPEG processing options, and in-camera high dynamic range. It shoots at 1.1 fps at full resolution and has in-camera lens correction that compensates for aberrations and distortion. All of this in a body that’s not too much bigger than a pro -DSLR (6.1 × 4.6 × 4.7″ 49 oz. – body only).

Pentax SMC D FA 645 55mm f/2.8 AL SDM AW. The 55mm f/2.8 lens (equivalent to a 43mm full-frame SLR lens) has a nine-blade circular diaphragm for nice blurring of out-of-focus highlights, and provides excellent image quality.
