Novoflex has announced prices for eleven adapters for the Micro Four Thirds standard, including Pentax K, Nikon F and Sony Alpha adapters with built-in aperture control rings. The adapters provide only a mechanical connection between the lens and the body but retain automatic metering for aperture priority mode and allow focusing to infinity. All should be in stock in the US by October, according to the US distributor, HP Marketing.

On adapters with aperture control rings, the control ring needs to be rotated to the fully open position (counter-clockwise for K and Alpha mounts, Clockwise for Nikon), before a lens is mounted. From this point, rotating the ring stops-down the aperture.
