I have a strange problem which I think may be pointing to a defective lens but what do you people think. The general problem is that image is saved is greatly overexposed compared to what I see in the viewfinder. Using an Olympus 14-42 lens: at 14-20mm, all OK in all modes. at above 20mm, image appears OK in viewfinder but is either greatly overexposed in iAuto, P and S mode. A mode is OK, not accurate but doesn't overexpose. Using an Olympus 40-150 lens, everything is good whatever the mode or FL. I have reset the cameras settings in case I've changed something unintentionally. Changing metering doesn't seem to make a difference. Any ideas?
