Originally posted by Not a Number The P30 is a manual focus body so it shouldn't matter if the lens has a Ricoh pin or not. Either the lens release button has gone wrong or perhaps the aperture lever was bent and is catching on something. Does the lens stop down when you use the DOF preview?
Otherwise all I can think of is to continue to fiddle about with the release button and twisting the lens back and forth and hope something works properly.
The lense stops down, battery is working, shutter operates and its metering.
I guess it can only be the release button. Sad times
