Hello,I'm a relative new D3200 owner and have been really enjoying it. I have the kit lens, along with the 55-330mm and a 35mm f/1.8 lens. I've been experimenting a little and may have changed a setting that I can't (don't know how to change back). So far, I've been primarily using the "presets", and have been using Aperture priority mode a fair amount with the 35mm lens. Once or twice, I've messed with exposure compensation and ISO settings. I've recently been trying to take pics in aperture priority mode with all three lenses and the shutter is staying open far, far longer than I think it should be. The only thing I can think of is I've set ISO or exposure compensation manually somewhere along the way, and it won't reset. If I'm in AUTO or one of the presets, shutter speed is fine this only happens in aperture priority. Any thoughts? Is there a way to clear all settings? Thanks for your input! I just got here, but am looking forward to exploring and learning more.Jim
