Fujifilm GF 1.4X TC WR Teleconverter

Extended Reach for Fujifilm's Medium Format Telephoto Lenses

The Fujifilm GF 1.4X TC WR Teleconverter is a G-mount accessory designed for Fujifilm's GFX medium format system, built for photographers who want to extend the reach of their telephoto lenses without compromising the exceptional image quality the GF system is known for. It magnifies the image by 1.4x while maintaining full communication between lens and camera body.

Extended Reach, Minimal Compromise

This teleconverter is made for photographers who need extra telephoto reach for wildlife, sports, or distant subjects. Attached to the GF 250mm F4 R LM OIS WR, it extends the focal length to 350mm (approximately 277mm in 35mm format equivalent), and with the GF 100-200mm f/5.6 R LM OIS WR, it extends the range to 140-280mm, in both cases with only a one-stop loss in exposure. Its advanced design maintains the original optical quality of the attached lens, with minimal deterioration in image performance even at the extended focal length.

Optical Performance and Build

The optical design consists of 7 elements in 3 groups, engineered to preserve the sharpness and rendering of the host lens as closely as possible. Weighing 400g and measuring 82mm x 27mm, it reflects the scale and build quality expected of Fujifilm's medium format lineup. The teleconverter features a weather-resistant construction that maintains the weather-sealing of the overall system, allowing reliable use in adverse conditions and temperatures as low as -10°C (14°F).

Full System Compatibility

The teleconverter retains full communication between lens and camera, fully supporting autofocus, exposure metering, image stabilization, and Exif data transmission, so photographers don't lose functionality when extending their reach.
