Fujifilm Fujinon XF 23 mm f/2.8 R WR
4. Image resolution
Let’s remind here that the best fixed focal length Fujifilm X lenses, tested that way, can reach as high as about 90 lpmm and the decency level is situated near 44-45 lpmm. So far the best resolution we measured while testing the Fujinon XF 18 mm f/1.4 R WR (93.5 ±0.9 lpmm), the Viltrox AF 27 mm f/1.2 (97.5 ±1.5 lpmm) and the Viltrox 75 mm f/1.2 (99.8 ±1.2 lpmm).
Now let's check how the Fujinon XF 23 mm f/2.8 R WR compares – its results in the frame centre and on the edge of the frame presents a graph below.

Taking into account the aperture fastness of the tested lens and its dimensions, the performance should be called excellent only. Already at the maximum relative aperture you deal with a very good level of over 71 lpmm; by f/4.0 the resolution increases to an impressive value of over 81 lpmm.
As if it wasn't enough the Fujinon 2.8/23 fares very well on the edge of the frame, a fact especially praiseworthy as you deal here with a pancake type of a lens. Even at the maximum relative aperture you see values over 60 lpmm and on stopping down the aperture this result improves even a bit. Because of that the tested lens is able to provide images of really impressing resolution practically in the whole aperture range and across the frame – a round of applause!
At the end of this chapter, traditionally, we present crops taken from photos of our resolution testing chart, saved as JPEG files along with RAW files we used for our analysis.
