Hello, yesterday I was attending a sport event with my girfriend shooting the camera. After I was done competing I myself wanted to take some shots, when I noticed that aperture on the m.zuiko 45 mm f/1,8 wont work. I could set whatever f-number I wanted on the camera dial, but the aperture was stuck at wide open. I thought that it might be failure of the lens, but it does the same thing with the 14-42mm f/3,5-5,6 II R. So it's something wrong with the camera operating the lens aperture ring I guess. I have tried to remove the battery. Tried a different battery. I have set the option reset lens after start on/off. Nothing worked so far. When I take a shot at f/1,8 or f/22 the DOF stays the same though the exposure is changed (I thing that's strange because the aperture should control the amout of the light going onto the sensor, but I guess the sensor compensates for preview in any way). Has anyone met the same problem, or better have you any idea what might be the solution to this? Thank you for answers and please excuse my rusty english. Jan.
