    Thumbs up Re: Experimental AF confirmation with manual lenses

    Unfortunately nothing there is either surprising or widely useful. At best implementors would have to sacrifice one fourthirds lens to chip one third party lens, and the chip would still communicate the original parameters.

    If the fourthirds specification is ever opened, however, third parties would be able to program their own chips, allowing all kinds of interesting functions:
    1. Adapter rings programmed with a focal length, allowing IS
    2. Automatic mechanical aperture control of OM lenses
    3. Full electronic control of some third party lenses, including autofocus and aperture
    4. Focus confirmation for any lens
    5. Autofocus control of anything one cares to hack together, including telescopes and the like, via widely available electronic focusers
    And that's just a few hacks. On a grander scale fourthirds could establish itself as a true standard and remove all doubt about a future tied to the whims of a single manufacturer. Olympus glass can easily compete on its merits alone, and the system as a whole would benefit from the increased security of widespread support.
