NX300 SUMMARYThe 20.3-megapixel NX300 is the most fully realized mirrorless, compact system camera Samsung has produced yet and one of the best on the market in its class. Though the camera is slightly bigger and heavier than its predecessors, the NX300's "retro modern" design looks great, and it's still highly portable. While the NX300 has the same resolution as the previous model -- which should be more than enough for most photographers -- the camera's APS-C-sized, CMOS sensor is brand new, adding on-chip phase detection autofocus for quicker and more accurate focusing. Image quality is also better, particularly in low light at high ISOs. A new processor has made the NX300 a faster performer than previous models, which were noticeably sluggish, while even better wireless connectivity tools make sharing photos almost as easy as with a smartphone.
