Does anyone here use an iPhone 4S (or similar) as the only camera on their ventures? The pictures it takes are pretty remarkable these days, and it also captures HD video very well. Since I take a phone with me on all hikes as a backup GPS and communication device, I am thinking of shedding the weight of my point-and-shoot camera. Yes, I know it has no optical zoom, and the quality won't be as good as a real camera (don't fall for the megapixel marketing), especially in various lighting situations. But the pictures it takes seem more than acceptable for most situations.
Do you use an iPhone as your primary camera while backpacking? If so, I'd love to hear your experiences and see some sample pictures that you've taken.
