Phredd: Why all the rage. It's good commentary on how good the iPhone 5s captures panoramas; not ultimate praise compared to dedicated cameras. If you'd rather take no photos than use a phone, go in peace. This wasn't written for you.
You can set the direction for panning. Just click the arrow for left or right panning. Simply turn the phone sideways to make a tall vertical pan. Very nice. It doesn't beat giga pixel images I shoot and stitch with PT GUI, but I would never take my DSLR in my back jersey pocket on all day bike rides. Great job Apple!
BeanyPic: As expected Great in Normal, Bright situations. Below average in Low light. Good try Nikon. Demonstrates that more MP's are not needed as most photographers know. Better luck next time Nikon.
So, he sees more shooting errors when the image is magnified dramatically, and thinks its an issue with the high mp sensor. I'll be taking this review with a huge grain of salt now.
