This is a medium format camera with digital back. They have existed for a while and are used only for professional purposes like making big advertisement posters etc. Regratably, the medium format camera is dying and I am not sure if the digital versions will make this trend change

I myself had a few very fine film cameras which I really loved (a Canon EOS 1N RS, a Contax G2 with 5 Zeiss lensses and some otheres) but I decided to sell them as the age of photography as I knew it came to an end in 2005
