Description
The 645D’s large 44x33mm CCD image sensor is the key to realizing the high-quality, true-to-life images that inspire every photographer
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. The 645D incorporates a large, high-performance CCD image sensor (approximately 1.7 times larger that that of 35mm-format models). Because of this, it provides superb image detail, unmatched by 35mm-format photography, and gives a boost to the creative aspirations of all photographers.
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.
