A few more K-mount lenses have left the building, so I bought some cheap treats for the NX300. An M42:nx adapter will arrive soon for the 80-200mm f/3.5, and a leather wrist strap will look good with the auburn faux leather of the camera body. The OIS 50-200 f/4-5.6 will get more use than the m42 tele I expect.. that is no cheap treat but the stabilized lens is worth owning as winter's gloom envelops the region. As to additional updates time will tell; hopefully an NX pancake prime or two will come along soon.
Tests have impressed with AF video, and the touchscreen focus-point shift does well. That feature reminds me of the GF1 micro-43 I once owned, but this sensor is both larger and more fully featured. So far so good. I recognize this camera will not compete with a K-3 for features, but for reasons that seem good to me this is quite satisfactory.
