The following chart presents a comparison between parameters of different mirrorless lenses with angles of view near 30 degrees. The Fujinon 2/50 sticks out with its complex optical build – it has more elements than the faster Samsung or the faster, stabilized Sony. The Olympus 1.8/45, assessed by us very highly, features the same number of elements and we think it bodes well for the Fujinon’s performance.

In the photo below the tested lens is positioned next to the Fujinon XF 35 mm f/1.4R and the Zeiss Touit 2.8/50M.

The Fujinon XF 50 mm f/2 R WR starts with a metal mount surrounding contacts and a rear element, about 25 mm in diameter. The element doesn’t move and hides inside the inner tube over 1 cm deep. The tube is excellently blackened and matted. There are no slits so you can be sure no dirt is going to invade the interior of the construction.

The proper body of the lens starts with a metal, immobile ring on which you see a focal length mark, a red rectangle, making an alignment with a camera easier, the serial number and information that the instrument was produced in Japan.

The next part is an aperture ring, 12 mm wide, most of its surface taken by metal ribs. In many Fujinon lenses I’ve tested so far such rings had too much slack but here the performance is practically faultless, allowing you to change aperture values every 1/3 EV stop.

Further on there is another immobile ring made of metal with information that the lens is sealed (“WEATHER RESISTANT”). Then you find a manual focus ring, 20 mm wide, completely covered by fine ribbing. It is a focus-by-wire construction which allows you very precise settings ( by the way they can be completely ruined by idiotic camera software that, during the photo preview, might change the focus on its own even if you work in the MF mode). Unfortunately the lens doesn’t feature any depth of field scale.

Behind the focus ring you get another metal part of the casing which turns smoothly into a hood mount.

The front element of the lens is 23 mm in diameter and surrounded by an inscription with the name and parameters of the lens along with a filter thread, 44 mm in diameter.

When it comes to the optical construction you deal here with 9 elements positioned in 7 groups. One element is both aspherical and made of low-dispersion ED glass. Inside, you also find a round aperture with nine diaphragm blades which can be closed down to f/16 at the maximum.

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