Hi Lluís, and thanks again!
Yes there is this small sound, when the camera is in "auto" , but I also hear similar sound when I push the aperture opening button. It Is a small cliking sound, like the motor wich doesnt start. If it is a mechanical problem, is it worth of fixing? I mean that I can alvwys use the external lightmeter, right? Camera seems working fine, exept this lightmeter problem. I have one test roll inside it, and Ishoot it and wait the results.
Like you said, it´s reilable camera. I hope.
All the best,
Antti
