Hi, try it with another lens ! The viewfinder tells you the result of the calculation regarding the incoming light and the aperture simulation resistor. If the closed aperture is not according to the resistor value, the LX will control a different shutter speed, because the final shutter speed is controlled after the aperture closed and the shutter opened. I had this happen with one lens, but the pictures came out OK ! That's one of the big advantages of the LX. If the problem remains also with another lens, I suppose the resistor of the aperture simulation is not OK. On the other hand your MZ-M gives the same metering. Are the pictures with the MZ-M and this lens correct exposed ? But a real quotation would be only possible with slide film, I think.
