I've been so impressed with the photos that I can take with my iPhone 5 I thought it would be fun to perform a comparison. Here is a screenshot of the Lightroom comparison view of three images taken of the same scene.
Top Left is taken with the D7000 - unadjusted, in camera,jpg Top Right is taken with the D7000 Raw, and adjusted in Lightroom 4. Bottom is taken with the iPhone, unadjusted
Cropping was done so the image proportions are the same.
