Will, is there a digital 4 lens camera? (something like the nikisha) which doesn't involve film?
Not that I know of. For a while I was exploring the idea of trying to make my own as a Kickstarter campaign but it’s too far too complex. Even mass producing a cheap single lens digital camera that takes good photos is a feat, let alone one with four lenses, four sensors, and a buffered image processor to intake the data. Gonna hope somebody smarter will figure it out.
