Here is a google translated Japanese website that claims there will be 3 adapters specific for Sony Alpha, Nikon and Pentax. The main break through is that the mechanism can adjust the aperture if the lens are made for electronic control aperture. Now you can enjoy wider range of lenses, including some sigma, tokina or tamron lenses for those mounts. But of course, no AF.
The rings has reach another sky high price which is about 25200 Jap Yen. If you have a big family of lens series under a brand from one of the above, you may consider. Otherwise, just explores more old gems from ebay. :toocool:
But a bad news to Canon user also, they are unable to develop one kind of this adapter because there is no "aperture stick" opened up for this adjustment.
Canon just hides all the mechanic parts.
