Viltrox 85mm f/1.8 vs Fujinon XF 90mm f/2 Comparison

Share

The brand new Viltrox 85mm f/1.8 autofocus lens for Fujifilm X is getting the more and more attention since FujiRumors started covering it with this hands-on test back in September 2018 (includes RAW samples to download).

This time Mattias and Andrew compare it also to the Fujinon XF 90mm f/2. Mattias used it on an X-Pro1 and X-E3, whereas Andrew on the Fujifilm X-T3. Their findings do not correspond always.

Check out the main points below:

Mattias (video above):

  • negligable size and weight difference
  • Viltrox a bit more solid build and smoother focus ring
  • Viltrox is not weather sealed and no aperture ring
  • both deliver excellent looking images
  • at crazy pixel peeping, the Viltrox is softer in the corners
  • Viltrox is less contrasty
  • Viltrox is a bit more prone to flare
  • both control well chromatic aberration and purple fringing, with Fujifilm having less fringing
  • autofocus is similar, with 90mm being a bit faster in low light
  • wide tracking and continuous AF, the Viltrox is consistently better
  • IQ slightly better on Fujinon 90mm

Andrew (video below):

  • he is impressed by the Viltrox 85mm f/1.8
  • Viltrox is all metal and well build
  • initially the Viltrox was a bit stiff to mount on the camera, but now it works smoothly
  • he misses that the Viltrox has no aperture ring
  • Viltrox originally designed for full frame, it’s bigger and heavier than needed for APS-C
  • Viltrox has a stepping motor, the XF90mm has a linear motor
  • sharpness: 90mm wins by a small margin in the center, but wins more clearly in the corners
  • Viltrox is best between f/5.6 and f/8. Get’s softer beyond f/8
  • Viltrox gives cooler results in terms of colors
  • In some cases, the Viltrox can have doubling bokeh and more jittery bokeh
  • bokeh balls are not nearly as perfect as on the 90mm f/2
  • The 90mm is good at 1:5, the Viltrox at 1:8
  • The 90mm focuses up to 1 second faster than the Viltrox
  • Viltrox has less reliable face tracking
  • Continuous AF: 74% of shots in focus on X-T3 with 90mm, and only 58% in focus with the Viltrox
  • Viltrox has more misfocused shots in general
  • Viltrox can improve AF in future via firmware update
  • Viltrox has assured they will keep up updating the lens, once Fujifilm releases new firmware updates, to make sure the lens will always work properly on Fuji bodies
  • the Viltorx exceeded his expectations and he is impressed
  • however, he will not use the Viltrox in his portrait shoots, due to unreliable autofocus
