Samsung is coming out with smart watches that would be a compact solution you could attach to the camera. Also the Android OS has extensive support
for running cameras. Both Nikon and Samsung have cameras running on the OS.
However I really don't understand why the MF companies don't get together and produce a standard shutter and protocol.
Standard shutter and put the control software in the backs. It's pretty simple stuff. Loads of point and shoots have had electronic leaf shutters for
years. It's really rather ass backwards the way it is today. Timing is done by the shutter and the back has to copy this timing. Would it not be much better for the back to
dictate the timing. You would still set the speed on the camera (slr) for ergonomic reasons, but the back would do the timing.
The shutter needs power, and those small android devices can probably not power the shutter.
The tech cam makers could together fund a new company that provided them all with some common components, but I think it's a too hard for them on the political level to collaborate, I think it would be quite hard for say Sinar, Cambo, Arca-Swiss, Alpa, Linhof to decide about funding, management and design directions, as they are quite fierce competitors too. It would be great though. Apart from shutters they could even make digital backs (with a precise and secure attachment mechanism for once), and have it all nicely integrated.
These companies are mainly mechanical factories too, their electronics is not exactly looking like a streamlined product from Sony but more as a lab prototype electronics-in-a-box. They need new knowledge to be able to design and manufacture an electronic product which is small, look great and has great ergonomics. The electronics-in-a-box type of product is not necessarily bad, they are working just fine in the studio, but out in the field and with hand-holdable equipment it would be nice with something small, smooth and well-integrated.
Rather than yet another poorly integrated electronics-in-a-box or required-software-in-a-computer-that-goes-obsolete-in-three-years I'd want a new mechanical shutter though, and that seems more likely to happen than an actual smooth well-integrated electronic solution.
