Samsung seemed to be throwing spaghetti at the wall when it introduced the original Galaxy Camera, but the device's following was enthusiastic even if reviews weren't. The follow-up Galaxy NX added a larger APS-C sensor in an interchangeable lens form factor. Today's announcement of the Galaxy Camera 2 and a refreshed Galaxy NX should please fans, but current owners should think twice before upgrading.
The concept for the Galaxy Camera is simple: take a good point-and-shoot and pair it with solid smartphone components to facilitate sharing. For the Galaxy Camera 2, only one half of that equation is warmed over to bring us this update. The original's 1.4GHz Exyos 4 Quad system-on-a-chip is swapped out for the 1.6GHz variant first seen in the Galaxy NX. Updates to the image signal processor bring additional image quality improvements, but the sensor and optics seem to be unchanged. That means it has the same point-and-shoot-sized 1/2.33" sensor and 21x zoom. Such a platform should produce better images than most smartphone cameras, but worse images than Micro Four Thirds cameras, let alone DSLRs with APS-C sensors.
Speaking of proper DSLRs, the Galaxy NX20 was the first interchangeable lens camera running a mobile operating system and the first Android device to expose manual control over all aspects of shooting. The updated NX30 benefits primarily from an updated image signal processor software package and from being packaged with a copy of Adobe Lightroom 5. That software package might be a big boost to value if it had been packaged with the Galaxy Camera 2; with the much more expensive NX30, though, it's less of a boon.
