Now bear in mind, I am not going to try to not make a judgement call as to which camera is better. Always remember, the best camera is always the one you have with you, and I am a firm believer in that; my photography adventures began on a Kodak EZ share 5 megapixel camera. It was a piece of crap, even for the time, but guess what? I took pretty good pictures, because the most important part of the camera is who's holding it.
We are going to divide cameras into 3 categories in this article for the sake of simplicity. Cell Phone Cameras, Compact Cameras, and Pro-Style Cameras. First is the cell phone camera.
Cell Phone Cameras
Now other advantages include shooting in the RAW format to preserve high quality color and detail, very good low light capabilities, full control over every aspect of the image. Images look more natural on pro-style cameras because the large sensor allows fine detail to be well defined and smaller areas to be in focus. Disadvantages include $$$$, if you are looking at a pro camera you are staring down at a minimum $400, for a new bare bones camera and 3x zoom lens, and additional lenses and accessories will nearly always be in the hundreds of dollars or more. Also these things are big, even the small ones will be bigger than the largest compact camera. And hopefully this isn’t too much of a problem but you will have to learn stuff. These cameras are only as good as their users, if you use it like a compact camera and leave it on full auto you could end up wondering why you paid $3000 for your Canon 5D mkIII to come up with pictures that are 5 times bigger than your old camera’s but look only slightly better.
