Its robust, weather-resistant build ensures reliability in challenging environments, making it the go-to solution for GFX shooters who need uncompromising performance on location. This teleconverter exemplifies Fujifilm’s commitment to delivering professional-grade tools that enhance the versatility and reach of the GFX lens lineup.
1. 1.4x Magnification Factor
The GF 1.4X TC WR multiplies the focal length of compatible GF lenses by 1.4x, enabling photographers to capture distant subjects with greater detail without physically moving closer. This optical extension is achieved with minimal impact on image sharpness and is optimized for the high-resolution GFX sensor. Compared to standard teleconverters, its design ensures edge-to-edge clarity, crucial for medium format imaging.This allows professionals to photograph wildlife, sports, or landscapes with increased reach while retaining exceptional image quality.
2. Advanced Optical Construction
Featuring 7 elements in 3 groups, the teleconverter utilizes high-grade glass and precision engineering to control chromatic aberration and distortion. Its optical formula is specifically tuned for the resolving power of GF lenses, ensuring no perceptible loss in detail or contrast. Multi-layer coatings further reduce flare and ghosting, even in challenging lighting conditions.This enables photographers to confidently shoot in high-contrast environments, knowing their images will be clean and color-accurate.
3. Maintained Autofocus Performance
The GF 1.4X TC WR preserves fast and accurate autofocus functionality with compatible lenses, thanks to its low-loss optical path and electronic integration with the GFX system. Autofocus speed and precision are only minimally affected, ensuring reliable subject tracking and focus acquisition. This sets it apart from many third-party teleconverters, which often degrade AF performance.This ensures that action and wildlife shooters can capture decisive moments without missing focus.
4. Weather-Resistant (WR) Construction
Built to the same WR standard as GF lenses, the teleconverter incorporates dust- and moisture-resistant seals at critical points. It is rated to operate in temperatures as low as -10°C, making it suitable for fieldwork in adverse conditions. The robust build quality matches the demands of professional outdoor photography.This provides peace of mind for photographers working in rain, snow, or dusty environments, ensuring uninterrupted performance.
- Weather sealing at key points
- Operating temperature: down to -10°C
5. Seamless Electronic Communication
The teleconverter supports full electronic communication between the lens and GFX camera body, preserving EXIF data, aperture control, and image stabilization functions. Firmware updates can be delivered via the camera body, ensuring future compatibility and performance enhancements. This integration is superior to many legacy teleconverters which often lack full electronic support.This allows users to maintain full control and metadata accuracy for efficient post-processing and workflow management.
6. Minimal Light Loss
The GF 1.4X TC WR introduces only a one-stop reduction in maximum aperture, maintaining excellent low light performance compared to higher-magnification teleconverters. This careful balance ensures that image quality and exposure flexibility are preserved, even when shooting in dim conditions. The optical design minimizes vignetting and maintains even illumination across the frame.This enables photographers to work in golden hour or low-light scenarios with minimal compromise to exposure settings.
7. Compact and Lightweight Design
Weighing just 400g and measuring only 15mm in length, the teleconverter adds minimal bulk to any kit. Its compact profile allows for easy transport and rapid deployment in the field, making it ideal for travel and location shoots. The design philosophy prioritizes portability without sacrificing durability or performance.This allows professionals to extend their reach without overburdening their gear bag, crucial for long days in the field.
8. Optimized for GF Lenses
The teleconverter is specifically engineered for use with select Fujinon GF lenses, such as the GF 250mm f/4 R LM OIS WR, ensuring optimal optical and mechanical compatibility. Its bayonet mount is precision-machined for a secure fit, and the optical path is calibrated to match the unique characteristics of GF optics. This targeted compatibility outperforms generic medium format teleconverters in both image quality and reliability.This ensures users achieve the best possible results with their existing GF lens investments.
9. No Image Quality Compromise
Rigorous testing and design ensure the GF 1.4X TC WR introduces virtually no perceptible degradation in sharpness, contrast, or color fidelity—a critical requirement for medium format professionals. The teleconverter’s optical formula maintains high microcontrast and suppresses color fringing, even at the extended focal length. This performance is on par with, or superior to, first-party teleconverters from other leading brands.This guarantees that fine art, commercial, and editorial photographers can deliver uncompromised image files to clients.
10. Easy Integration and Operation
Mounting and unmounting the teleconverter is simple and secure, with clear alignment marks and a robust locking mechanism. Its operation is fully transparent to the user—no special menu settings or adjustments are required. The device is engineered for plug-and-play functionality, allowing for rapid response to changing shooting scenarios.This streamlines field workflows, letting photographers adapt quickly to evolving subject distances.
