Our editorial take on the Samsung 20-50mm F/3.5-5.6 II ED I-Function (NX) Black Lens
The Samsung 20-50mm F/3.5-5.6 II ED I-Function is a compact wide-to-standard zoom designed for the Samsung NX mirrorless system. It offers a versatile 40.5mm filter thread and incorporates Samsung's I-Function control, which allows direct adjustment of aperture, shutter speed, and other settings via a ring on the lens barrel. At an MSRP of $83 (used, excellent condition), it positions itself as an affordable entry point for NX shooters looking to expand beyond a kit prime.
The lens covers a practical focal range for everyday shooting, from moderately wide landscapes to standard portrait and street work. The variable aperture design (F/3.5-5.6) keeps size and weight down but limits low-light performance and shallow depth-of-field capability. Extra-low dispersion (ED) glass aims to control chromatic aberration across the zoom range. As a legacy NX-mount lens, its utility is tied to Samsung's discontinued mirrorless line, making it best suited for existing NX users rather than those starting fresh in a current system.
- Compact and lightweight wide-to-standard zoom range
- I-Function ring for direct setting adjustments
- Affordable used pricing for NX system users
- Variable F/3.5-5.6 aperture limits low-light and depth-of-field control
- NX mount is discontinued with limited ecosystem support
