FUJIFILM XF 16-50mm f/2.8-4.8 R LM WR Lens

The FUJIFILM XF 16-50mm f/2.8-4.8 R LM WR Lens is a compact, lightweight standard zoom lens designed as a replacement for the long-running XF 18-55mm kit lens, built for APS-C-format Fujifilm X-mount mirrorless cameras. Delivering a 24-76mm full-frame-equivalent focal range, it’s a versatile, take-anywhere lens well suited to a broad range of scenes and subjects, from landscapes to intimate portraiture, and designed to resolve the detail captured by Fujifilm’s latest 40-megapixel sensors.

Optically, the lens covers its 16-50mm range with a variable maximum aperture of f/2.8 at the wide end narrowing to f/4.8 at full telephoto, down to a minimum aperture of f/22. The 11-element, 9-group optical design includes three aspherical elements and three ED (Extra-low Dispersion) elements to minimize aberrations and deliver sharp, clear results across the zoom range, and a rounded 9-blade diaphragm contributes to smooth, pleasing bokeh.

Autofocus is handled by a Linear Motor (LM), delivering fast, quiet autofocus well suited to both stills and video, with strong tracking and subject-detection performance. A standout feature of this lens is its internal zooming mechanism, keeping the lens’s overall length fixed at approximately 7.14cm (2.8 in.) throughout the entire zoom range, both for a compact, consistent form factor and for long-term mechanical reliability compared to extending zoom designs. The lens offers a close minimum focusing distance of 0.24m (9.45 in.), yielding a maximum magnification of 0.3x, giving it useful close-up capability alongside standard zoom shooting. A traditional aperture ring is included on the barrel, consistent with Fujifilm’s manual-control-oriented design philosophy, adjustable in 1/3 EV steps across 19 stops.

Build quality includes weather-resistant (WR) sealing at multiple points along the barrel, protecting against dust, moisture, and freezing temperatures down to -10°C (14°F). The lens accepts a 58mm filter thread, measures approximately 65mm in diameter, and weighs just 240g (0.53 lb.), making it genuinely compact and lightweight for everyday carry. It does not include optical image stabilization.

As an APS-C-specific lens, the XF 16-50mm f/2.8-4.8 R LM WR is designed exclusively for Fujifilm’s X-mount mirrorless system.
