Have yet to be impressed with the camera in any of the iPhones I've owned. Though I do appreciate the HDR abilities to capture subjects in low light.
But I'm also a right tool for the job kind of guy. I don't expect the pictures from my phone to be great, and I don't expect the phone calls from my DSLR to be great either.
