This scanning camera back for 4x5 view cameras was released in 2000 and we are still using it today (2019). The image quality is still beyond anything I have seen, with a resolution of 12,600 x 10,500 pixels each for R, G and B from a tri-linear CCD. Combined with a Rodenstock Digital Lens the results are spectacular. Perfect for art reproduction and still life photography.

Being a scanning back it is slow and can't be used for any imagery with motion. Scanning time can be as long as 20 minutes, so you will get motion artifacts that makes the image unusable.
