It is also worth noting that the aperture ring doesn't mechanically change the aperture. Take the lens off the camera, turn it and nothing happens. In effect its a switch which communicates with the camera to tell it what aperture you are using. The manual focusing ring is the same. So you have cosmetically a "retro" type lens, but in essence its a modern electronic lens very similar to NEX & m4/3 lenses. This is not to say that it isn't good quality, in fact it is VERY good indeed. However I can't help but feel that the whole thing is a bit of a con and intended to just add a bit of "retro chic".
