Fujifilm X-Series users will soon be able to purchase a 2x teleconverter compatible with two of the company’s telephoto zoom lenses, delivering a maximum equivalent focal length of 1219mm for its interchangeable lens compact system. The XF2X TC WR teleconverter will be weather and dust-resistant when used with the X-T1 and X-Pro2 camera bodies combined with the XF50-140mm F2.8 R LM OIS WR and XF100-400mm F4.5-5.6R LM OIS WR lenses.

Fujifilm says that the teleconverter will deliver an angle of view equivalent to that of a 1219mm lens on a full frame camera when it is used with the 100-400mm lens, once the crop factor of the APS-C format is taken into account.

The converter consists of nine elements in five groups and adds 30.2mm to the physical length of the camera/lens set-up. With the 2-stop light loss, the AF system of the X-cameras will revert to contrast detection with the 100-400mm F4.5-5.6 lens, but phase detection will still work with the 50-140mm F2.8. Both lenses will need a firmware update in order to operate with the new teleconverter so that adjusted aperture and focal length values can be recorded in the EXIF data and displayed on-screen.

Fuji suggests that the converter will be compatible with other lenses in the X-Series range, and has set up a website on which it promises to post information about future lens compatibility.

The Fujifilm XF2X TC WR teleconverter will be available in June priced $449/£349. For more information visit the Fujifilm website.


Press release:

Fujifilm announces the FUJINON XF2X TC WR Teleconverter

High-performance weather and dust resistant teleconverter with excellent optical design to be added to the X-Series interchangeable lens line-up in June

FUJIFILM Corporation (President: Shigehiro Nakajima) is proud to announce that the new FUJINON TELECONVERTER XF2X TC WR, a teleconverter extending the telephoto area of some X Mount lenses*1, will be added to the mirrorless digital camera X-Series interchangeable lens line-up in June 2016.

The FUJINON TELECONVERTER XF2X TC WR is a high-performance teleconverter, 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.

In addition, thanks to the unified design when mounted to a compatible lens*1, 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.

*1 Compatible lens (As of May 19, 2016)
XF50-140mmF2.8 R LM OIS WR = 100-280mmF5.6 with teleconverter mounted (Equivalent to 152-427mm on a 35mm format)
XF100-400mmF4.5-5.6 R LM OIS WR = 200-800mmF9-11 with teleconverter mounted (Equivalent to 305-1,219mm on a 35mm format)

1. Main Features

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

  • Construction of 9 elements in 5 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 2x teleconverter, excellent imaging performance with great aberration suppression is still achieved.
  • The aperture becomes two f-stops higher when the teleconverter is mounted, and the camera displays and records information reflecting the change in aperture and focal length.

(2) Autofocus performance

  • Phase detection AF is still available when using the XF50-140mmF2.8 R LM OIS WR with the 2x teleconverter mounted.
  • Contrast Detection AF is still available when using the XF100-400mmF4.5-5.6 R LM OIS WR with the 2x teleconverter mounted.
  • Accurate focusing at super-telephoto focal lengths with shallow depth of field is possible thanks to the AF performed by the image sensor, thanks to the ‘Live View’ feature on the cameras.

(3) The optical image stabilization performance

  • The camera’s optical image stabilization performance*2 is unaffected by the addition of the teleconverter

*2CIPA guidelines, at telephoto end.

(4) Weather and dust-resistant and -10°C low-temperature operation

  • Using the teleconverter with a weather-resistant camera, such as the FUJIFILM X-T1 or X-Pro2 mirrorless digital camera and the FUJINON XF50-140mmF2.8 R LM OIS WR or FUJINON XF100-400mmF4.5-5.6 R LM OIS WR lens does not affect the weather resistance of the system.

(5) 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.

4. Support Information

A firmware update is required for the FUJINON XF50-140mm F2.8 R LM OIS WR and FUJINON XF100-400mm F4.5-5.6 R LM OIS WR lenses in order to provide full compatibility. This firmware is planned to be available at the beginning of June 2016. Please note that when updating firmware, make sure to update the latest camera firmware before updating the lens.
