Detailed features of Ricoh Pentax 645D.

Image size is a very important factor in advanced photography: the larger the image size, the more faithfully the ambience and sense of depth can be described, resulting in colour-rich, fine-detailed images.

Distinctive imaging characteristics different from those of 35mm format. Rich gradation, natural depth-of-fiend description at open aperture, and crisp image definition at smaller apertures. The large image circle and broad sensor plane of the medium-format image sensor assures these benefits — factors essential for producing super-high-quality, true-to-life images unrivaled by 35mm-format counterparts. In addition, since a medium-format lens has a longer focal length than a 35mm lens with the same angle of view, it offers a better details of textures and makes the subject stand out more sharply against beautifully obscured background.

While the low-pass filter (LPF) is effective in minimizing the adverse effects of false colours and moiré, it can cause a deterioration in image sharpness. Because the Ricoh Pentax 645D was designed for the highest resolution in mind, it features a LPF-free CCD unit, which can optimize the resolving power of the lens and the image sensor without compromising the overall image resolution. Thanks to its super-high resolving power, the 645D delivers high-quality images so sharp and vivid that even every leaf of a tree in a scenic image stand out clearly and individually.

The Ricoh Pentax 645D features the new PENTAX 645AF2 lens mount, designed to accept a vast selection of smc PENTAX 645-series interchangeable lenses — from wide angle to telephoto — all of which offer exceptional image descriptive power. With an FA 645-series lens mounted, the 645D retains autofocus operation. The new D FA 645 series is designed to minimize flare and ghost images, while retaining the superb descriptive power of conventional 645-series lenses, to produce sharp, bright images even at edges.

The Ricoh Pentax 645D’s high-performance 14-bit A/D converter converts the analogue signals output by the CCD image sensor to data-rich, multi-gradation digital signals (with a maximum of 16,384 gradations), which are then forwarded to the PRIME II imaging engine. Thanks to its high-speed data-processing capacity and new algorithm, this high-performance imaging engine instantly processes as much as 40 megapixels of data to produce super-high-quality images, which are truly satisfying even to the most demanding photographers. This sophisticated imaging engine can even compensate lens aberrations for the photographer.
