Both are weather-resistant Fujifilm telephoto zooms for APS-C that accept Fuji's 1.4x and 2x teleconverters and offer about 5 stops of stabilization. The XF 100-400 (January 2016) is the super-tele of the line with a focus limiter, twin linear motors and a lens hood with a window for a polarizer. It weighs 1,375 g. The XF 70-300 (January 2021) is the compact option at 580 g, about 800 g less. According to Fujifilm it focuses to 0.33x, the 100-400 only to 0.19x.
