Just picked up an iphone 5.
The camera is quite an improvement over the camera on the iphone 4 which I've had for the past few years. As with any new toy I've been playing around and shooting more with it. I've also been using 2 really good mobile phone apps- VSCO cam and Snapseed.
I've used a bunch more in the past but have decided to just keep these 2 on my phone.
As far as cameras go, the Fuji XPro-1 is still my main squeeze but the iphone5 is the camera that's always in my pocket.
