Excuse me, but there have been multiple iPhone images used on magazine covers in the past and this is on the cover of Billboard Magazine right now. You really are showing that you don't know what you are talking about when you make that claim. There are real Bill boards size images using iPhone images that were done with iPhones. Did you not read what I wrote about the pixel size on movie screens and the resolution of what the human eye can actually see? It is the angle of acuity that counts, not the number of pixels and how far away the view is that counts. A 1080 pixel view with half inch pixels on a 45 foot movie screen at 60 feet viewing distance is fine for most viewers and it will look the same as that same 1080 pixels on their HD TV at 10 feet with far smaller pixels. . . But the number of pixels remain the same. It's the appearance to the viewer that counts, not the megapixels of the screen or camera.
An iPhone is capable of taking 4K video, which is 8,294,400 pixels with 24 bit color resolution. That is FAR beyond the requirements of any magazine cover in six color printing separation. . . And in fact only the highest quality magazines are ever printed to that standard. Several large double page spreads have been printed in National Geographic in full color taken from iPhones by professional photographers, including the covers.
So, Excellence, you really don't know what you are talking about. The best camera is the one you have with you.
Not my opinion, dude.
