Verdict

The Pentax 645D is a professional medium-format digital SLR featuring a 40-megapixel CCD sensor (44 x 33 mm) designed to deliver exceptional image resolution and a wide dynamic range without an anti-aliasing filter. Known for its rugged, weather-sealed magnesium alloy body, it offers compatibility with legacy 645-system lenses, a 77-segment metering system, and an 11-point SAFOX IX+ autofocus module. While it excels with superb color depth, dual SD card slots, and intuitive ergonomics, its primary drawbacks include a limited ISO range (100–1600), a slow burst rate of 1.1 fps, and the lack of video recording capabilities.
