I have been looking to get a new camera. I want to be able to take pretty good pics, and learn more about photography. I found the Canon PowerShot S2 IS at circuit city and it seems like a pretty good camera for the price. I was really thinking about getting a digital rebel, but being that its $350 more, I am trying to figure out what to do. I really don't know that much about photography right now, but I want to learn. I found out that on this powershot you can get a lens adapter set so I can mount better quality lenses onto the camera, just like the digital rebel. Now I know the powershot isn't a SLR camera, but how much does that improve a camera? I am thinking about getting this one and learning, and if I stay really into photography I would step up and get a rebel or something like it. any thoughts?
