The **FUJIFILM GF 1.4x TC WR Teleconverter** is an essential accessory for photographers looking to extend the reach of select **FUJIFILM telephoto and telephoto zoom lenses** in the **G-mount** lineup. This high-quality teleconverter magnifies the image by 1.4x, making it ideal for sports, wildlife, and landscape photographers who need enhanced focal length without compromising image quality. Designed for use with compatible lenses like the **GF 250mm f/4 R LM OIS WR** and the **GF 100-200mm f/5.6 R LM OIS WR**, this teleconverter extends the focal range by 40%, resulting in an effective reach of 350mm and 140-280mm, respectively.

One of the teleconverter’s most valuable features is its ability to maintain **full communication between the lens and camera body**, ensuring that essential functions like **autofocus, exposure metering, image stabilization**, and **Exif data transmission** remain fully operational. Importantly, it only incurs a 1-stop loss in brightness, which helps to preserve the exposure and functionality of the lenses even at extended focal lengths.

The **weather-resistant (WR) construction** of the GF 1.4x TC WR Teleconverter makes it durable and reliable in adverse environments, with seals that protect against dust, water, and temperatures as low as 14°F. This durability complements the rugged nature of FUJIFILM’s GFX system, enabling photographers to shoot confidently in challenging conditions without affecting performance.
