The "FUJINON TELECONVERTER XF1.4X TC WR" is a high-performance teleconverter capable of multiplying the focal length of mounted lenses* by 1.4x. Although the aperture becomes one f-stop higher when mounted, the teleconverter features an excellent optical design with a construction of 7 elements in 3 groups to maintain the optical performance of the original lens. Also, thanks to the unified design when mounted to a compatible lens*, the teleconverter is weather and dust-resistant and operates at temperatures as low as -10°C. This makes it possible to be used with confidence outdoors when used with the weather and dust-resistant FUJIFILM X-T1 camera body and XF50-140mmF2.8 R LM OIS WR lens.
