Extend the reach of your GF 250mm f/4 R LM OIS WR lens with the GF 1.4x TC WR Teleconverter from FUJIFILM. The G-mount converter magnifies the image by 1.4x and retains full communication between the lens and body, enabling metering, autofocus, and image stabilization as well as the transmission of Exif data. Additionally, the teleconverter is designed to maintain the weather resistance of the entire FUJIFILM system with a sealed construction that reduces the chances of dust, water, or even the cold from affecting performance.
