Fujifilm FUJINON XF 1.4X TC WR Teleconverter The "FUJINON TELECONVERTER XF1.4X TC WR" is a high-performance teleconverter capable of multiplying the focal length of compatible lenses*1 by 1.4x. When mounted, the teleconverter increases the lens’ aperture by one f-stop, however its sophisticated optical design constructed of 7 elements in 3 groups maintains the optical performance of the original lens. in addition, thanks to the unified design when mounted to a compatible lens*1, the teleconverter is weather & dust-resistant & operates at temperatures as low as -10°C. This ensures it can be used with complete confidence outdoors with the weather & dust-resistant X-T1 camera body & XF50-140mm F2.8 R LM OIS WR lens. Main
Features: High image quality design which maintains the optical performance of the original lens The teleconverter’s construction of 7 elements in 3 groups maintains the optical performance of the original lens. By using the optimum image quality parameters for the overall characteristics of the original lens & 1.4x teleconverter, an excellent imaging performance with great aberration suppression can be achieved even when the focal length is multiplied by 1.4x. The camera displays & records information reflecting the change in aperture & focal length when the teleconverter is mounted. The camera’s autofocus performance is unaffected by the addition of the teleconverter An AF speed equivalent to that of the lens by itself is still achieved when the teleconverter is mounted. Thanks to mirrorless cameras’ “ Live View” Contrast Detection autofocus, shooting at minimum aperture values is still possible despite the f-stop being increased by mounting the teleconverter. Also, accurate focusing at super-telephoto focal lengths with shallow depth of field is possible thanks to the AF performed by the image sensor. Weather & dust-resistant & -10°C low-temperature operation Using the teleconverter with a weather-resistant camera & lens, such as the "FUJIFILM X-T1" premium mirrorless camera & the "FUJINON Lens XF50-140mm F2.8 R LM OIS WR", does not affect the weather resistance of the system. High-grade subtle appearance The teleconverter’s high grade metal exterior has been designed with the X system in mind. When attached to a compatible FUJINON lens, the two products appear as one single lens. *A firmware update is required for the camera body as well as the "XF50-140mm F2.8 R LM OIS WR" lens in order to provide full compatibility. This firmware is planned to be available on October 29th 2015. Please note that when updating firmware, make sure you update the camera firmware before updating the lens*
