Note: these are scanbacks and you will need a camera like the Linhof 4X5 for about $4,000 to 10,000.

Better Light’s digital scanning backs do not capture an image of the subject in front of the camera all at once, but rather by physically moving a unique, highly-optimized trilinear color image sensor smoothly across the image plane, building up the image one line per color at a time.

This means that scanning backs are typically used only for photographing relatively stationary subjects illuminated by continuous light. Continuous advancements in image sensor and processing hardware and software over the past decade have made these high-resolution capture devices much faster and easier to use, but scanning backs will probably not be used for fashion or sports photography any time soon.

An article that discusses a product comparison testing of super high resolution cameras

Building your own high resolution (120-490 megapixel) camera using a flatbed scanner as a backend. Costs about $1000-1300. The 490 megapixels is based upon 2400dpi scanners. Currently 6400dpi is available for flatbed scanners So the resolution of a DIY system would be over 2 gigapixels.
