Comrades, I just bought a wornout Olympus Pen ee-3. I am sure it's a great camera, even though the one I've got is king of rusty in some specif parts, my guess is that it is a very old piece. Anyhow... I've been finding myself confronted by some specif problems; it's loaded, but it won't shot when the red flag is on. It's on from the 25 ASA to the 400 preset, (is that the ISO?). After that the red flag is off and it seems to be shotting perfectly. My concern is that in the configurations where the red flag is off, the pictures will come too dark (rembebering that it's from 4 to 35). Am I doing something wrong? Or the already used camera should be the problem? Furthermore, I can shot some pictures when the red flag is on by pressing the shotting button very strong and fast, which makes the camera bounce and when I do that, even though the flag would be appearing at that specif condition, it doesn't appear. I think it's because of the way I press the button.
Here there are some pictures of this "fine" piece: (the first one indicating the red flag, the preset was at 400)
