Samsung S 50-150mm f/2.8 ED OIS Review
Sharpness at 50mm
The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Samsung S 50-150mm f/2.8 ED OIS lens was attached to a Samsung NX1 body, which in turn was mounted on a sturdy tripod.
The full frame at 50mm
Centre sharpness is quite good at f/2.8, and improves further upon stopping down to f/4. The effects of diffraction become visible at f/16 but do not become a serious problem until you hit f/22. The edges are commendably sharp too, peaking at at f/5.6 and f/8.
