Fujinon GF 1.4x TC WR Review

The Fujinon GF 1.4x TC WR is a teleconverter designed for Fujifilm's GF medium format system. It multiplies the focal length of compatible GF lenses by 1.4x, extending reach for wildlife, sports, and telephoto work without the size and weight of a longer prime. At just under $1,000, it offers a more affordable path to extra focal length than purchasing an entirely new telephoto lens. The WR designation indicates weather resistance, keeping it in line with the build quality of Fujifilm's GF lens lineup.

Teleconverters inherently reduce the effective maximum aperture by one stop with a 1.4x multiplier, so users should expect some impact on low-light performance and depth of field control. Compatibility is limited to select GF lenses, so confirming your glass works with this TC is essential before purchase. For medium format shooters who need occasional extra reach and already own compatible lenses, this teleconverter fills a practical niche in the GF system.
