Yea, hopefully in one of the next versions like the iPhone 7 or 8 would be a second or third camera. I want a longer lens just built in. They are tiny and they could set up a second button to activate the longer lens camera.
I want the capability of a Canon 5D Mark III with a 18 to 400 zoom lens packed into my iPhone. And I want it as a free upgrade!
I will wait for the iPhone 9 to match or exceed the Canon EOS 5DS / 5DS R 50 Megapixel camera.
