You will be amazed when you first see images shot by the Pentax 645D: they embody a completely new world of visual expression, a world made possible only by medium-format digital cameras. Features 40 effective megapixels and a large, 44 x 33mm CCD image sensor, the Pextax 645D faithfully reproduces even the slightest differences in ambience. This is the ultimate imaging tool, created by Pentax for those particularly discerning photographers who demand nothing but the highest image quality.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 description, unmatched by 35mm-format photography, and gives a boost to the creative aspirations of all photographers.Thanks to its approximately 40 effective megapixels, the 645D delivers super-high-resolution images equal in quality to those captured by the high-end digital camera backs used at professional photo studios. Its resolving power is far superior to that of 35mm-format digital SLR cameras or film-format 645 cameras. Even when printed on large-format papers (measuring as large as 420mm by 297mm), you are assured of high-density, true-to-life artwork. When printed on the larger papers (measuring as large as 1,189mm by 841mm) used for photo exhibitions, the difference in resolution becomes even more evident. Sharply defined details make your images more fascinating and inspiring.
