Austin Mann took an iPhone 5 and 5s to Patagonia to compare the cameras:

> All the fancy new features like fingerprint scan are nice and nifty but as a travel photographer, all I really care about is what this camera can do.  
> We climbed mountains, hiked to glaciers, slept in the wilderness… all the while documenting it with these two awesome little camera phones…

Several of the side-by-side comparison shots are amazing. Especially when comparing the dynamic range of the two cameras.
