Digital Camera World Verdict

There are currently no super-telephoto lenses for the Fujifilm GFX medium format system so I like that the Fujinon GF 1.4X TC WR teleconverter boosts the reach of the pair of prime and zoom telephoto lenses in the current catalog, and with very little impact on image quality or overall performance.

Pros

  • +

    1.4x boost in reach and magnification

  • +

    Excellent performance/image quality

  • +

    Tough weather-sealed build quality

Cons

  • -

    Only compatible with 2 lenses so far

  • -

    Expensive for a teleconverter

  • -

    Relatively weighty

Fujifilm is a world-renowned photographic company that needs no introduction. It’s been going about its business since 1934, but the medium-format GFX system is comparatively in its infancy, having been launched in 2017. It certainly hit the ground running though, and I’m a big fan of the growing range of excellent Fujinon GF lenses for its medium format cameras.

Although the range is continually expanding, there are currently no GF-mount super-telephoto lenses. At the time of writing this review, the longest telephoto offerings are the Fujinon GF 250mm F4 R LM OIS WR prime and the Fujinon GF 100-200mm F5.6 R LM OIS WR zoom. Factor in the large medium format image sensor of GFX cameras and these lenses give a maximum reach equivalent to using roughly a 200mm or 160mm lens on full-frame cameras, respectively. With high hopes to be one of the all-time best teleconverters, the Fujinon GF 1.4X TC WR aims to add extra reach and versatility to the GFX system.
