@ Craig:
Great shot you took there using your adapter! I can't believe that such a small camera that can capture shots of space so clearly!
Had a look into those SLR lenses for the iphone. They don't look really handy. Looks like it would be a bit difficult to hold the heavy lens, keep the phone steady and use a touch screen to capture the shot instead of pressing a button imo, (although I hear the latest iPhones, have an option of using a button to take a photo).
