Fujinon XF 100-400mm F4.5-5.6 R LM OIS WR - Telephoto Zoom, Optical Image Stabilization, Weather Resistant, Fast Autofocus
The Fujinon XF 100-400mm F4.5-5.6 R LM OIS WR establishes itself as a professional-grade super-telephoto zoom lens designed for Fujifilm X-mount mirrorless cameras. Tailored to sports, wildlife, and action photographers, this lens addresses the critical need for extended focal reach, uncompromising optical clarity, and reliable performance in demanding conditions. Its advanced optical formula, robust weather sealing, and class-leading image stabilization system make it a go-to solution for professionals who require precision and flexibility across a wide range of challenging shooting scenarios.At the core of the XF 100-400mm is Fujifilm’s expertise in lens engineering, leveraging high-transmittance ED glass elements and a twin linear motor autofocus system. The lens delivers edge-to-edge sharpness, minimal chromatic aberration, and fast, silent focusing—key attributes that set it apart from earlier XF telephoto options and competitors like the Canon EF 100-400mm L IS II. With its lightweight magnesium alloy construction and intuitive manual controls, the XF 100-400mm empowers photographers to capture distant subjects with confidence, whether tracking fast-moving wildlife or freezing the action at sporting events.
1. Super-Telephoto Zoom Range (100-400mm, 35mm equivalent: 152-609mm)
Covering an impressive focal length range of 100-400mm (equivalent to 152-609mm on APS-C), this lens enables photographers to capture distant subjects with exceptional clarity and detail. The extended reach is ideal for wildlife, aviation, motorsports, and outdoor event photography, eliminating the need to physically approach sensitive or inaccessible subjects. This allows professionals to frame tight compositions and maintain image quality even at maximum zoom.
2. Optical Image Stabilization (OIS) - 5.0 Stops
Featuring a sophisticated 5.0-stop optical image stabilization system, the XF 100-400mm significantly reduces the risk of camera shake, especially at longer focal lengths and slower shutter speeds. The OIS unit compensates for both angular and shift movements, ensuring sharp handheld images and smooth video recording, even in low light performance scenarios. This enables photographers to shoot confidently without a tripod, expanding creative possibilities in dynamic environments.
3. Advanced Optical Formula - 21 Elements in 14 Groups
The lens incorporates 21 elements in 14 groups, including 5 extra-low dispersion (ED) elements and 1 Super ED element, effectively minimizing chromatic aberration, color fringing, and distortion. This optical construction delivers high-resolution, high-contrast images throughout the zoom range, outperforming older Fujinon telephoto zooms and rivaling premium full-frame alternatives. This allows users to achieve professional image quality with consistent sharpness from center to corner.
- 5 ED elements
- 1 Super ED element
- Multi-layer HT-EBC coating for flare resistance
4. Twin Linear Motor Autofocus System
The twin linear motors provide fast, quiet, and precise autofocus performance, essential for tracking moving subjects in sports and wildlife photography. The system is optimized for rapid subject acquisition and minimal hunting, even in low-contrast scenes, outperforming the single-motor designs in previous XF telephoto lenses. This ensures that photographers can capture decisive moments with accurate focus and minimal lag.
5. Weather Resistant (WR) Construction
With 13 weather seals at 12 points along the barrel, the XF 100-400mm is engineered to resist dust, moisture, and low temperatures down to -10°C (14°F). This robust weather resistance matches Fujifilm’s flagship X-series bodies, enabling consistent performance in challenging outdoor environments. This allows professionals to shoot with confidence in rain, snow, or dusty conditions without compromising lens integrity.
6. Lightweight Magnesium Alloy Body
Despite its super-telephoto reach, the lens weighs only 1,375g (3.03 lb) without the tripod collar, thanks to a magnesium alloy chassis and polycarbonate exterior. This lightweight design reduces fatigue during handheld shooting and makes the lens highly portable for travel and fieldwork. This enables longer shooting sessions and easier transport compared to bulkier full-frame telephoto options.
7. Fluorine-Coated Front Element
The front element is coated with a high-grade fluorine layer, repelling water, oil, and fingerprints for easier cleaning and maintenance. This protective coating preserves optical clarity and reduces downtime in adverse weather or dusty environments. This ensures photographers can maintain peak image quality with minimal effort in the field.
8. Internal Zoom and Focus Mechanism
The XF 100-400mm employs an internal zoom and focus mechanism, meaning the lens does not extend or rotate during operation. This design maintains consistent balance, enhances weather sealing, and allows the use of polarizing filters without adjustment. This enables smoother handling and more reliable performance during rapid zoom changes.
9. Compatible with Fujinon Teleconverters (XF1.4X TC WR & XF2X TC WR)
This lens is fully compatible with Fujifilm’s dedicated XF1.4X and XF2X teleconverters, extending the maximum reach to 560mm (equivalent to 853mm) or 800mm (equivalent to 1,218mm) respectively, with minimal loss in image quality. Autofocus and OIS functions remain fully operational, providing flexibility for extreme telephoto needs. This allows photographers to adapt quickly to distant or elusive subjects without sacrificing performance.
10. Removable Rotating Tripod Collar
The included tripod collar is both removable and rotatable, offering stable mounting for long exposures and panning shots. The collar’s ergonomic design facilitates quick transitions between landscape and portrait orientations, supporting a wide range of shooting styles. This allows for increased stability and versatility when working with heavier camera setups or shooting from a tripod.
Summary
The Fujinon XF 100-400mm F4.5-5.6 R LM OIS WR stands out as a top-tier telephoto solution for Fujifilm X-series users, combining advanced optics, powerful image stabilization, and rugged weather resistance in a lightweight, portable package. Its extensive zoom range, fast autofocus, and compatibility with teleconverters make it the lens of choice for professionals demanding reach, reliability, and image quality in fast-paced and unpredictable environments.Whether capturing elusive wildlife, dynamic sports action, or distant landscapes, the XF 100-400mm empowers photographers with the flexibility and performance needed to excel. Now available at ebphotovideo.com, this lens represents a significant leap forward for X-mount shooters seeking professional results in the field.
