Samsung NX 50-200mm F4-5.6 OIS User Reviews

++ nice color rendition ++ high sharpness ++ good correction of CAs - no aperture ring and plastic housing, no manual aperture control with NX 1000

The lens is quite good but most copies are decentered on one side, especially evident at 50 mm. For the cheap price though, it is quite ok. The center is sharp. Can't expect too much beyond that.

Very sharp, with nice rendering.  Focus may hunt at the long end.  Good build quality.  The image stabilization was not quite as good as I expected.
