Nice shots. How big is that clam? I really like the second pic the way it shines above the mouth.

Maybe like you mentioned, your camera is compensating for the magnifying glass. I've only tried this with the Kodak easyshare camera that I have so I'm not sure which cameras it will work with.
Also, how close are you putting the camera to the magnifying glass? Sometimes it takes a little experimenting to get a good picture. I sometimes will have the camera 4-5 inches away from the magnifying glass and then use the zoom from the camera to get some of the shots.
