Metabones and Leica have shown that electronic adapters can maintain full function of lenses with electronic controls on cameras they were never intended to be used with. The same can\'t be said for mechanical lenses.
Disagree.
If you\'re given access to the right SDK (or hack it), yeah, you can do it electronically. But there\'s absolutely no guarantee you will be. Remember, even Zeiss didn\'t originally have access to the Canon data to make the ZE lenses, or even enough info from Nikon to transmit just EXIF data. And Metabones still only has electronics working for Canon not Nikon (Red has Nikon, but apparently it was an incredibly complex undertaking and most people don\'t have as much money to throw away as they do). And those are for modern, still-in-production, extremely-widely-used systems. Mostly you\'re SOL. Hell, not all cinema cameras can even read the LDS system.
With a mechanical linkage, you can always just build something. Metabones Nikon G adapters with an aperture ring are one basic example. But you could go further than that. No one has bothered because of ROI, but you could absolutely build an adapter that mechanically held the aperture of a Nikon F or Leica R lens open until you fired a photo. The only \"communication\" with the camera that would require would be detecting an electrical discharge, same as a flash sync cable. Maybe you\'d need a cord connected to the hotshoe or another port on the camera, but I bet you could do it right from the lens mount.
