I am not a photographer, but was in an art market with some a few weeks ago. A friend and I were talking to a photographer that was new to the show who had absolutely stunning closeup nature pictures. One that really blew me away was a 3'x3' picture of a magnolia blossom with a bee flying over one of the petals. An amazing shot. I mentioned it to him, and he pulled out his new iPhone. Said, "Don't tell anyone, but I took that one with this."

Yes, a pro needs to know all of the equipment, lighting stuff, etc., but the newest phone cameras can do some pretty amazing stuff.
