I just bought an F3 hp from KEH in EXC grade. It looks pretty much new to me but doing some quick test I noticed that setting the camera to auto, stopping down the lens to 22 and leaving the lens cap on the lens, if I release the shutter, it will remain open until I change the speed setting. I thought it would remain open for 8 sec. Does this indicate a problem with the camera or is it normal? I just shot a test slide film and Iím waiting the results on Monday.

Thanks.
