Sony E-mount has proven to be incredibly popular and LEX Optical announced their intention to release the first film E-mount camera a few months ago as a result. Now they have released their Schematics and Firmware on GitHub if you’re interested in trying to build your own camera. LEX Optical is definitely worth keeping an eye on if you enjoy shooting film and already own a lot of E-mount glass, but I’m curious to see how tinkers might build off their design going forward.
