At first I thought that it would be very difficult to find any direct rivals of the Fujinon XF 50 mm f/1 R WR and compose a comparison chart. A very attentive search of our database showed that there have been some fast 50 mm lenses designed for mirrorless cameras with APS-C sensors released earlier and you can find them in the following chart.

In the photo below the Fujinon XF 50 mm f/1 R WR is positioned between the Fujinon XF 56 mm f/1.2 R and the Voigtlander Nokton 25 mm f/0.95, designed for Micro 4/3 sensors.

The tested lens starts with a metal mount surrounding contacts and a rear element, about 28 mm in diameter. That element doesn't move and is hidden into an inner tube just several milimeters deep. That inner tube is excellently blackened and matted, without any slits through which dirt and dust might invade interior of the construction.

The proper barell starts with an immobile, metal ring that turns wider very quickly. On that ring you can find a focal length marking and a red square, making an alignment with a camera easier, the serial number of the instrument and information that it was produced in Japan. There is also an inscription „WEATHER RESISTANT” meaning that the lens features gaskets that protect it from negative influence of harsh weather conditions.

Then you see an aperture ring, 13 mm wide, most of its surface covered by metal ribbing. In many Fujinon lenses I've had an opportunity to test these rings were quite loose but here the performance is practically perfect, allowing you aperture control every 1/3 EV step.

The next part is a manual focus ring, 33 mm wide and completely covered by fine ribbing. It operates electronically and allows you very precise settings (which, by the way, can be completely ruined by idiotic software of the body as it can change sharpness during preview even if you've chosen the manual mode). Unfortunately, you won't find any depth of field scale on the lens. The focus throw amounts to an angle of about 180 degrees. That value increases when you turn the ring very slowly.

Behind the focus ring you see another immobile part of the casing made of metal and it turns smoothly into a hood mount.

The front element is flat, 59 mm in diameter, and surrounded by an inscription with the name, and parameters of the lens along with a non-rotating filter thread, 77 mm in diameter.

When it comes to optical construction you deal here with 12 elements positioned in 9 groups. One of elements is aspherical and two other are made of low dispersion ED glass. Inside you can also find a round aperture with nine blades which can be closed down to a value of f/16 at the maximum.

Buyers get in the box: both caps, a hood, and a soft pouch.
