Samsung 16-50mm f/2-2.8 S ED OIS NX

 
Lens Reviews / Samsung Lenses i Lab tested

Most people tend to think of image stabilization as being mainly for telephoto lenses. While it's true that their longer focal lengths tend to magnify the effects of camera shake, image stabilization can provide a very useful assist at wider angle focal lengths as well; anyone who's ever tried to blur the image of a waterfall, while keeping the surrounding landscape tack-sharp knows exactly what I'm talking about.

At the 16mm focal length setting we see about two and a half stops of hand-holding image stabilization. With OIS turned off, we see results we'd expect with the one-over-focal length rule of thumb: 100% sharp images at a 1/15s shutter speed. With OIS turned on, this improves to 90% sharp images at 1/4s, and 50% sharp at 1/2s.

Zoomed in to 50mm, we see even better performance, perhaps around three stops of hand-holding stabilization. With OIS engaged, we get 90% sharp images at 1/8s, and 50% sharp images at 1/4s - pretty impressive at 50mm!

IS systems tend to provide more benefit to less-stable shooters than very steady ones, so most users will see the same or greater amounts of shake reduction as we measured here. You can read more about our IS test methodology here: SLRgear IS Test Methodology, v2.
