Verdict

The Fujinon XF 100-400mm f/4.5-5.6 R LM OIS WR impressed me quite a bit - not only in the lab but also in the real life. Honestly I was almost about to purchase the lens from the rental company (but I kept my sanity). The center sharpness is very high throughout the zoom range. The borders/corners are also very sharp between 100 and 300mm. Expect slightly softer corners at 400mm though (but then who cares here). Lateral CAs are not a real issue. Most users will keep image auto-correction activated thus neither distortions nor vignetting are issue in this case. The native characteristic isn't quite as good here though. The quality of the bokeh is very decent for such a lens - at least technically - but don't expect wonders regarding the depth-of-field at conventional focus distances.

Fujifilm is targeting the semi-pro and professional market with this lens so the build quality is on very high level (although it doesn't touch the Canon EF 100-400mm USM L IS II or Sigma 150-600mm Sports here). Most body parts are made of metal and the broad, rubberized control rings are fun to use. The AF is both fast and silent (for a mirrorless camera setup). Needless to say but the image stabilizer is an essential ingredient on such a lens and Fujifilm's version offers an effective gain around the 3-4 f-stop mark ... depending on your coffee level.

Fujinon lenses don't tend to be budget items and I'm afraid that your bank account manager will cry a little if you decide to go for this one ... 1800EUR/1900US$. However, it is worth it and there are no other options for Fujifilm cameras in this class anyway. Highly recommended!
