My Sony Nex 5 keeps coming up with the same error. “Can not recognize lens. Attach it properly” From reading I am finding out the gold contacts are either dirty or not making contact. I am hoping dirty. Any thoughts on cleaning them? Thanks in advance for your time. TnT
A gentle rub with a pencil eraser should do the trick. Don't let the flakes get on the sensor.
