The iPhone 6 camera is interesting. Not sure what I think yet. I hadn't really taken any pics till today.
Here is an iPhone 6 vs S5 shot, taken within 5 seconds of each other, same distance away from object, focused on the ship logo and Perry Ellis lettering. No zooming or anything.
iPhone is first, S5 is second in the sequence. Natural light in the first, artificial in the second.
I find the iPhone takes warmer, sharper pics, with better color reproduction.
