Testing the new Fujinon XF 100-400mm


after an anxiously long wait, I have purchased the Fujinon lens XF100-400mm F4.5-5.6 R LM OIS WR.

My first impression was the pure satisfaction of owning one of the most highly awaited lenses of 2016, mainly due to it being the first Fujifilm’s lens made specifically for wildlife and sports photographers. However, as I waited for its arrival, I’ve been reading some negative comments about its AF performance, which is a point to deal with.

Since I started taking photography seriously, I’ve always tried to find out which is the best and most affordable lens, to cover all the photographic needs and get the best possible results, that’s why I previously owned the TAMRON SP 150-600mm F5-6.3 VC USD before moving from Nikon to Fuji.


The XF100-400mm is well finished and solid, you can feel it as soon as you get a hold of it. It has 21 glass elements divided in 14 groups, not enough? The front element of the XF100-400mm is coated with fluorine which works as water resistant / rain-repellent, that is the reason why is WR (water resistant) lens. The zoom is fast and butter smooth, it goes from 100mm to 400mm in a tick.

Its weight is only 1.375gr. Attached to the XT-1, total weight is under 2kg, enough to walk around and feel free to shoot pretty cool pictures without missing a tripod, at least for a while.

AF is accurate and fast in normal lighting conditions. It loses accuracy and speed in low light conditions, but this is not a low light lens, it is FF4.5-5.6. The AF tracker mode is pretty much the same. It works well in normal lighting conditions, making easy to track a bird while flying and getting most of the pictures focused. That is when you have to turn on the Optical Image Stabilization (OIS) which helps to get nice shot. However I’m still struggling and desiring/dying for a faster and accurate Auto Focus. Looks like this issue comes from the XT-1, which is not made or ready to support a powerful lens like the XF100-400mm.


Image quality is amazing. The lens is remarkably sharp at every focal length. Imagine quality and bokeh are the best features. I’m stunned with the sharpness, colors and quality. The bokeh is soft and creamy, even at f 5.6 you get nice results.


If you are looking for a wildlife and sport lens, don’t hesitate to get it. Perhaps the XT-1 or X-Pro1 are not ready yet to get the most out of the XF100-400mm. Nevertheless everyone is expecting if the future XT-2 will take advantage of the XF100-400mm. An expensive equipment helps, but it’s more important to have experience and good skills. I’ve already covered my photographic needs buying it, and I don’t need to wait for the new XT-2 to get better shoots, but if Fuji develops the AF, it will help me to get better ones.

    Beautiful shots and thank you for sharing you EXif data, it helps as a starting point with using this lens.

    Just as an aside, I feel that “Wild red kite landing on the ground” could do with a little fill light on the bird, it is a fantastic shot though and one that I wish I had taken!


    • Hi Margaret,
