Marco Arment:
Like many of the people likely to be reading this, I bought a digital SLR a few years ago and developed a photography hobby. Then, also like many of you, my iPhone’s camera slowly took over my casual photography needs, and I stopped bringing the big SLR with me most of the time. The iPhone camera was good enough for most uses.
I have never owned a nice camera. One day I may spring for something like a GX1, but right now my iPhone is not only “the camera I have with me,” it’s also the best camera I own.
The iPhone’s abilities as a camera have significantly improved over the years. If your budget or your interest in photography don’t warrant a high-quality camera, fortunately it’s safe to say that Apple will continue to make the iPhone into a great camera.
