The Samsung NX 20-50 mm f/ 3.5-5.6 ED II is a kit lens for Samsung NX cameras, including NX1000, though it can be bought separately.
Though the lens is not so tiny as the Samsung NX 30mm Pancake Lens, its collapsible design makes it rather compact (39.9 mm in transport position vs 56.6 mm in operational state). The front element rotates on focusing.
The iFN button allows you to take advantage of various mode settings your camera supports.
The AF motor is a bit slower than that of the Samsung 18-55mm, besides you can feel high-frequency vibration. The lens features manual focus by wire, so the AF motor is switched on by turning the focus ring.
The lens has no OIS. Angle of view 70.2˚ ~ 31.4˚.
Equivalent focal length 31-77 mm (FF equivalent).
Equivalent aperture ratio f/5.4-f/8.6 (FF equivalent).
