Fujifilm unveils its largest telephoto yet, the XF 100-400mm f/4.5-5.6

In addition to four new cameras yesterday, Fujifilm unveiled a massive new telephoto zoom lens, the XF 100–400mm f/4.5–5.6 R LM OIS WR.

The unveiling of this lens was no surprise, as it’s been on their roadmap for quite some time. But nonetheless, it’s a very welcomed addition to their X-mount lenses.

Constructed of 21 elements in 14 groups, the XF 100–400mm f/4.5–5.6 features five extra-low dispersion (ED) elements and one ‘super extra low’ dispersion element, which help reduce chromatic aberration and ghosting.

In full frame equivalents, the lens’ focal length is 150–600mm, making it Fuji’s biggest telephoto lens yet and a perfect match for wildlife photographers.

The lens features twin linear motors to power the autofocus capabilities and uses Fuji’s Optical Image Stabilization (OIS) to give up to 5-stops of vibration compensation.

To match Fujifilm’s just-announced X-Pro2, the XF 100–400mm f/4.5–5.6 is weather-sealed and is capable of functioning at temperatures as low as 14ºF.

The Fujinon XF 100–400mm f/4.5–5.6 lens will hit shelves next month for $1,900.
