Pentax 645D Medium-Format Camera
If you think Nikon’s P7000 sounds powerful, wait till you get a load of this monster. The Pentax 645D is a medium-format camera, offering a 44mm-by-33mm, 40-megapixel sensor that’s about 1.5 times the size of a full-frame DSLR sensor. It also uses a different lens mount and system than Pentax’s DSLR cameras. This super-sized camera offers a weather-sealed body made out of magnesium alloy, and it offers dual SD/SDHC card slots to store massive, 7264-by-5440-pixel images. For JPEGs, that translates to a file size of about 25MB per image. Yikes.
