Double the reach of your XF 50-140mm f/2.8 R LM OIS WR and XF 100-400mm f/4.5-5.6 R LM OIS WR lenses with the XF 2x TC WR Teleconverter from Fujifilm. The X mount converter magnifies the image by 2x 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.
