When the wife and I went to Tent Rocks Monument yesterday, we saw about an equal number of people shooting with smart phones versus actually cameras. I was doing both. I had my 6D in tow and was taking pictures abut every 10 feet! But then every once in a while, I'd pull out the Cell Phone and snap a few with that just so I could text them to friends and family. But no way could I get the same quality of photograph with a cell phone as I did with my DSLR. A tiny microscopic sensor with a 1/4 diameter piece of glass isn't going to produce the same quality of photograph as a full frame sensor with Canon L series optics. Not that iPhone photos are bad - they are good for what they are, but just not the same thing.
