Samsung — 16-50mm f/3.5-5.6 Power Zoom ED OIS compact motorized kit zoom, Samsung NX
The Samsung NX 16-50mm f/3.5-5.6 Power Zoom ED OIS arrived around 2013 as a compact, electronically driven kit zoom for the NX300-generation cameras, replacing bulkier manually zoomed kit lenses with a slim, retractable design suited to hybrid stills-and-video shooting.
Mounted natively on Samsung's APS-C NX bayonet, it spans a 24-75mm full-frame-equivalent range at f/3.5-5.6, using ED glass to control chromatic aberration and built-in optical image stabilization. Zooming is motorized rather than mechanical, controlled by a rocker or ring depending on mode.
The power-zoom mechanism gives smooth, consistent zoom speed useful for video pans, at the cost of a brief motor lag compared with a direct manual zoom ring. Its collapsed size keeps NX bodies notably slim for a standard zoom, favoring portability over handling feel.
Since Samsung ended NX production in 2015, this lens is now a used-only accessory tied to secondhand bodies. Check that the retracting barrel powers on smoothly, that the zoom motor is quiet without grinding, and that OIS engages, as its electronics see more wear than a mechanical zoom.
