Before accusing others of ripping off Alpa I think we could agree that Alpa's ripping off all of us. there is not such a thing as an Alpa camera anyway, what makes up the camera in that particular case is the lens, the lens has the diaph, the shutter and helicoid focus system, end of the story, the Alpa bit is just a glorified piece of aluminium alloy, it's so out of whack and poorly machined that you have to use a shim packer in order not to screw the pics on your digital back. I dont need shims on my Contax 645 and P25+, and guess what ? I have autofocus, you bring me to tears with you Alpa rubbish!!!!!
