I thought it would be handy to have a thread all about the camera.
For starters here is one of the more thorough run-downs of all the features of the camera being tested:

It notes that the Auto and HDR modes gave them the best results, and also commented on my own pet peeve, the generally slow shutter speed:
Our next stop was a luxury showcase, a great place to find very photogenic items sitting under very unflattering lights. Switching between Auto and HDR, we managed to snap a few good images with interesting composition and color. At this point we came across the S4 camera’s biggest weakness: shutter speed. A few images lacked crispness because we couldn’t always hold our hands steady and the shutter isn’t lightning quick. Compared to the HTC One, which is super fast, the S4 is about a half second slower.
...we experimented with using Voice Control. With this on, all you have to do is say ‘Smile’ or ‘Cheese’ or ‘Capture’ to snap a picture. It cut down on that last second shakiness that comes from tapping the screen. In Settings, you can also make the volume button a shutter trigger – another way to keep the phone steadier.
I took some decent photos with the S4 so far but would agree that the shutter lag is aggravating. If anyone has any better tips about reducing shutter lag, please post them!
