The Pentax 645D is the digital kid in the celebrated 645 family of medium format cameras, swapping medium format filmstock for a 44×33 mm 40 megapixel sensor. To maximize resolving power, Pentax says the sensor does not use a low-pass filter. The camera has a magnesium alloy frame and diecast aluminium chassis, reinforced glass covering the three-inch LCD, and is dustproof and weather resistant. The digital 645 will accept existing smc Pentax 645 interchangeable lenses, and other 645 system components too. Pentax Canada says a “limited number” of cameras will be available at authorized Pentax dealers in November.
