The main drawbacks are an average number of megapixels, meaning your images won’t retain their quality when enlarged, and poor functionality in low-light situations. The ISO still beats an iPhone, but it’ll still leave you turning on the flash.
Amazon customer Mary Hight says:
“Wasn’t sure I liked this camera when I first got it. But went out one night and took pictures of the moon and they looked like a professional took them from space! I got so many comments about the awesomeness of the pictures! Did MUCH better than my digital SLR which doesn’t have the zoom capability that this has. Also took a picture of a sunflower from over a friend’s shoulder while I was sitting on a chair on her patio using the zoom function (the sunflower was at least 50 yards away) and it came out crisp and clear and every hair on the stems and leaves showed in perfect focus. It was an awesome picture too! This camera can’t take the place of my digital SLR, but it has its place in my camera repertoire that is matched by nothing else. This is my first Canon product (I was a diehard Nikon user) and I like its ease of use. I am a hobby photographer and I’m very glad I invested in this camera.”
