I've had the Panasonic Lumix DMC-ZS10 for about a year and absolutely love it. However on my last trip I noticed some spots on my photos. Looking at my lens there appears to be specs of dust on the inside of my lens. It's past the first piece of glass and resting on the inside glass. Is there an easy way to get at that? Does this happen often? I'd hate to get a new camera just for that, but it really ruins some photos depending on the light.
