Simple fallacy here, you don't have electronic lenses. You have mechanically-coupled lenses with electronic meter coupling that you're adapting to a pure electronic mount.
The stop-down mechanism would be fairly complex, mostly due to size limitations. You could include it (and someday somebody will), but it's a much more difficult excercise than the electronically-coupled adapters for Micro-4/3rds (which cost well over $100 btw). You're taking the adapter froma simple design which is expensive enough to manufacture that even the cheap chinese knockoffs cost $50 to a far more complex design that would retail for a significant fraction of the camera cost. -Adam On Thu, Feb 25, 2010 at 1:00 AM, P.
