I have an NX with the 28-80mm f3.5-5.6 and a 70-200mm f3.5-4.5. Lenses are excellent, with great build quality. Autofocus is OK, not as fast as Nikon or Canon, but accurate. Built-in flash is OK with ISO 400 under 13 feet. Camera is a bit boxy and plasticky, but has a great set of features, once you learn how to use all the bells and whistles. The NX lenses are hard to find at a reasonable price. I gave up on the system because of this. You can buy a Nikon F100 with three or four lenses for less than an NX with two lenses. Too bad the system is dead.
