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.
