Fujifilm Fujinon XF 90 mm f/2 R LM WR
3. Build quality
It is clear that the slower Fujinon, designed to work on smaller sensors, is also physically bigger and heavier than typical full frame 1.8/85 lenses. Inner focusing mechanism, a fully sealed casing and a possibility to focus already from 0.6 of a meter are features which make it stick out in this group.

The Fujinon XF 90 mm f/2.0R LM WR starts with a metal mount and a contact plate which surround a rear element of the lens, about 2.5 cm in diameter. The element is hidden inside the casing over 1 cm deep. The interior of the tube around it is black and nicely matted and the element itself doesn’t move.
 |
The proper casing starts with a smooth, immobile ring with a red dot, making the alignment with a camera easier, the focal length mark, the serial number and an inscription ‘MADE IN JAPAN”. Further on you see an aperture ring. It is well-damped, allowing you to change the aperture value every 1/3 EV step. It is as wide as almost 12 mm and over half of that width is taken by ribbing. The next part of the lens is a smooth, immobile ring which almost begs for a depth of field scale – unfortunately the producers decided to leave it empty. It is a result of electronic relay of the focus ring.
 |
Moving on you see a ribbed manual focus ring which is 42 mm wide and fairly the biggest part of the entire casing. The ring’s work is based on electronic relay so in order to move the elements the lens has to be attached to a live camera. The ring is a joy to use, with both the smoothness of movement and proper resistance. Running through the whole range needs a turn through an angle of about 360 degrees when the ring is turned fast.
 |
Behind the manual focus ring you find a small part of the casing which turns into a hood thread (and the dedicated hood is added in the box).
The front element of the lens is 45 mm in diameter and it doesn’t move. It is surrounded by a ring on which there are inscriptions with the name and parameters of the lens, along with a non-rotating filter thread, 62 mm in diameter.
 |
When it comes to the optical construction you deal here with 11 elements positioned in 8 groups. As many as three elements are made of low dispersion ED glass. Inside there is also an aperture with seven diaphragm blades which can be closed down to f/16.
Buyers get both caps, a hood and a soft pouch in the box.
