My main concern is using existing alpha lenses. Between a 10mm/2.8, a 35mm/1.4, a 50mm/1.4, and an 85mm/1.4 I have about $3000.00 invested in glass. My fear is any adaptor Sony provides won't be as compatible as I hope. Given the glass to sensor distance on these new cameras compared to the current alphas, I figure there's about an inch of room to fit an adaptor tube and maintain the correct focal distance. But can Sony jam mechanical aperture control and the focus drive motor in there as well? I fear what we'll get is auto-aperture control with manual focus, perhaps with some kind of beep or onboard light to tell you when focus is good.
