We got this camera as a christmas present and I have a couple of questions. First off....it has an adapter so that you can attach a lens. What kind of quality am I going to get if I do this? Having a point and shoot with a decent lens can I expect something close to to the quality I could get with an SLR and a lens? Also.....if I were to put the adapter would it improve the quality of the photos? I know that might sound stupid but my thinking is that having that adapter, which looks like a small lens, would cut down on some of the light right off the camera.
