Re: Obvious
I disagree - I have a Nokia 1020 and a Sony RX1 (full-frame, 35mm f2 Zeiss lens). In quite a lot of areas, the 1020 can outperform the RX1 (recrop, focus speed, portability, even low light & dynamic range), particularly given the typical end-use, which is posting on the web at a significantly smaller size & resolution that most cameras. In those circumstances, you'd be hard pressed to differentiate the two, same goes with pictures out of an iPhone 6 or an LG G2/G3, all of which have vastly better cameras than any dedicated hardware less than ~$700.
There are certain areas that are still problematic for some phones (DOF, low light, high iso), but modern phone cameras are miles better than quite a few dedicated cameras from several years ago.
As someone who shoots a lot and has owned a lot of camera gear, from very cheap to absurdly expensive (think red dot), I'm leaning so much on the cameras in my iPhone & the 1020 that I rarely use the higher end gear. It's just not necessary to take fantastic pictures - most higher end phones from the last few years are good enough if you are a decent photographer. And to be a decent photographer, you must take a LOT of pictures with whatever camera you have at hand, not expensive dedicated gear.
And, yeah, if you pixel-peep, the phone cameras might not pass muster, but specs don't create great pictures...
