Updated 11/17 – The Fujifilm XF 100-400mm f/4.5-5.6 R LM OIS WR lens is a fabulous optic. Here is a gallery of photographs taken by Damien Lovegrove using it on X-Pro2 and X-T2 cameras.

The XF 100-400 is a substantial lens with a long helicoid meaning it extends when it is zoomed. The build quality is wonderful and despite its size the lens is surprisingly lightweight. I have found the mounting bracket that comes with the lens to be very useful because I use a monopod when shooting portraits with the 100-400. I mount the lens on the monopod and hang the camera off the back.
