Model: SAM-NX50-20MM The Samsung NX 50-200mm f/4-5.6 ED OIS III is a telephoto zoom lens (77-308mm equivalent) designed for Samsung NX-mount cameras, featuring iFunction (iFn) technology for manual setting adjustments. It includes optical image stabilization (OIS) to reduce blur, making it suitable for distant subjects and portraiture. Key Features and Performance i-Function Technology: Allows quick access to camera settings (shutter speed, aperture, ISO) via a ring on the lens, providing real-time previews. Optical Image Stabilization (OIS): Minimizes camera shake for clearer photos. Optics & Focus: Features a 0.98m (approx. 3.2 ft) minimum focus distance. Versatility: Ideal for travel, wildlife, and sports, often used as a companion to the 18-55mm kit lens. Design: Lightweight and compact for a telephoto lens, with a black finish to match most NX bodies. Compatibility and Availability Mount: Compatible only with Samsung NX-mount cameras (e.g., NX1, NX300, NX500, NX30). Market Status: As Samsung has exited the camera market, this lens is primarily available through third-party sellers on sites like Amazon.com.au and eBay. Considerations The lens is generally considered sharp for its price point but is not designed for low-light, handheld shooting at maximum zoom, according to user reviews. It is not a dedicated macro lens, but it performs well in long-distance photography.
