FEATURES

Teleconverter for X Mount lenses

 

High image quality design which maintains the optical performance of the original lens

Construction of 7 elements in 3 groups maintains the optical performance of the original lens.
By using the optimal image quality parameters for the overall characteristics of the original lens and 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 and records information reflecting the change in aperture and 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 and dust-resistant and -10°C low-temperature operation

Using the teleconverter with a weather-resistant camera and lens, such as the “FUJIFILM X-T1” premium mirrorless camera and the “FUJINON LENS XF50-140mmF2.8 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.
