Extend the focal length by 2x without comprimising image quality
The high-performance teleconverter is capable of multiplying the focal length of mounted lenses*1 by two. It features excellent optical design with a construction of 9 elements in 5 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 X-T1 and X-Pro2 camera bodies, and the XF50-140mmF2.8 R LM OIS WR and XF100-400mmF4.5-5.6 R LM OIS WR lenses.
