(Bill shoots pretty much all his photos with an iPhone, has been doing it for a few years. I've finally come around to doing this. Both of us still use the big cameras (him a Nikon, me an Olympus OM-D) for serious shoots, but the iPhone for every day shots. The new iPhone 6S has a super new camera.)
