I'm shotting an alpha 350. I've recently come into a lot of md and mc mount lenses and had to buy a converter ring so that the hardware would fit together. The problem is that the camera doesn't sense when a lense is attached to it and therefore locks the shutter, the end result being, obviously, that I can't soot. Is there some way, any way, possible that I can override the software in my camera body that locks the shutter in the response to the "no lense attached" sensation that it perceives?
