These are 100 percent crops from the center of our test scene. The good news is the Galaxy Camera 2's photo quality isn't considerably better than the first-gen model, so no need to upgrade for that reason. They aren't any worse, either (also a good thing), and like that camera, the GC 2 is best suited for outdoor daylight use, but does well in low-light as long as you take advantage of its features.
This isn't a camera for pixel peepers, though, and there's enough noise at ISO 800 that you won't want to enlarge them or heavily crop in. But, hey, with so many Android editing app options at your fingertips, even some color noise can be masked easily enough.
Basically, it's not a camera you should consider purely for its photo quality: There are better options between $400 and $500 ranging from dSLRs and mirrorless compacts to bridge cameras with more zoom range and enthusiast compacts with bright lenses. Consider it because it's much more than just a camera and can be a lot of fun.
