In 2014/2015 DHW (Rolleiflex) designed and built a new electronic shutter to replace their venerable Rollei electronic shutters using a microchip controller which operates via USB. These they had working at 1/1000th speeds and controlled via USB. I was sent this one unit to look at. It's a working prototype, but no software really exists for it. I sent this to a tech for phase one via digital back dealers to look at around that time and the IP for these was later purchased by Phase One. It seems a lot of it went into Phase One's newly introduced electronic shutters. This shutter is functional but you would be on your own trying to get it to work. I'm selling it more as a very collectible item, I actually only know of two pieces every being made, and as such an interesting part of Rollei History. Rolleiflex has been at the forefront of imaging technology many times, including development of Medium format digital backs in the 1990's. Much of what they have developed has found its way into cameras from other brands.
