Fujifilm
This 2x teleconverter doubles the reach of Fujinon XF50-140mm and XF100-400mm lenses while maintaining autofocus speed, adding just 172g, and offering full weather sealing down to -14°C. It accurately relays aperture and focal length data to the camera, keeping EXIF metadata precise for post-processing. Best for portrait and travel photographers who need to extend the XF50-140mm to a 100-280mm equivalent without carrying a separate, heavier lens.
