In PART 1 of his review, jonasjacobsson tested the autofocus speed of XF 50-140 (on a X-T1). The subject? A dog running full speed in any direction. So how did it work? From the conclusions.

“The toughest test was for sure the first one, when he came towards me, resulting in 5 missed shots. Otherwise, for the most part, the lens performed admirably. Fast and accurate. And like I stated above, some of the missed once are a result of me not being used to shoot fast-moving dogs and it was really hard to predict the movement sometimes, so do keep that in mind. Without a doubt this is the best lens suited for action and sports among the Fuji lenses. In terms of autofocus speed the XF 50-140 is miles ahead of the slower XF 55-200, along with many other advantages like weather sealing and a fast constant aperture of f/2.8. It is however also almost 2.5-3 times as pricy as the older sibling. Once you lock on target the lens tend to keep that focus very well unless you do a some drastic movement that might interfere.”

In PART 2 of the 50-140 review, jonasjacobsson judges the IQ of the lens.

Also engaged tested the XF 50-140 and they say:

“Image quality is fantastic throughout regardless of focal length, with pleasingly sharp details and accurate focus. Without Fuji’s current speed king, the X-T1, I wasn’t able to test out the upper end of its autofocus abilities, but it performed quickly enough on my trusty X-E2. As for bokeh, out-of-focus background elements were generally smooth and not distracting, meaning this should be a solid portrait lens if that’s your thing.”
