I think you're confused as to what professional photographers do. I'm talking about pro sports photographers, or wildlife photographers, or photojournalists in a war zone, and so on.

Cell phones will do fine to get snaps of grandma blowing out the birthday candles, or selfies on vacation... but they have a very long way to go to be any threat to the professional camera/lens market.

SHEESH! CementJungle. . . You literally are not paying attention! Who do you think these photographers that I have been posting LINKS to are?

• JUST exactly WHO do you think Benjamin Lowy is? An AMATEUR????Apparently you didn't bother to go to his website. . . or do any research about his CV and his photographic work for TIME. Lowy is both a SPORTS photographer and a correspondent in a WAR ZONE! Lowy is the quintessential professional photographer you describe, and he has been doing it with his iPhone, yet you dismiss him probably because YOU DIDN'T LOOK!

• Or how about the professional National Geographic photographer?

• Or how about this Professional photographer takes stunning nature and wildlife photos using iPhone?

• Or perhaps this chap isn't a pro sports photographer: Pro Photographer (The Guardian's Dan Chung) Using His iPhone To Photograph the Olympics"?

• And then when Pro Sports photographer Brad Mangin says 18 iPhone 4s Baseball photos of his were published by Sports Illustrated, he must be delusional about the camera he used, right?

Apparently, you jumped to the conclusion that just because the photographers I linked to before were using their iPhones to take photographs, they must not be professionals. . . just people making money taking pictures. Obviously, you reasoned, they could not be "professional"; they aren't using "professional equipment." I said then that I could keep posting links. I was not lying.

Against all these professional photographers who are actually doing what you say is not possible, and showing their published work done with iPhones, we have YOU, Cementjungle, denying it is possible or reasonable based on what? Your unsupported opinion. Sorry, I have posted link, after link, after link to articles and websites of actual professional, published photographers using iPhones for their work refuting your unsupported assertion. . . and on your side just you, repeating the same old, same old. You are completely outweighed by the evidence.
