Fujifilm Fujinon XF 90 mm f/2 R LM WR
4. Image resolution
Let’s remind here that the best fixed focal Fujifilm X system lenses tested that way can go as high as 73-75 lpmm and the decency level is situated near 42-43 lpmm. Now let’s see how the tested lens compares here. An appropriate graph with MTF50 values in the centre and on the edge of the frame is presented below.

When it comes to the frame centre already at the maximum relative aperture you get excellent results, reaching almost 72 lpmm. By f/2.8 the Fujinon’s 2/90 resolution increases to a record-breaking value of 78.5 ±0.6 lpmm. It’s enough to say that so far no other lens, tested on the Fujifilm sensors, has managed to fare so well. I think you don’t need any other commentary here.
When it comes to the edge of the frame you don’t have any reasons to complain either but it has to be said the edge is not as impressing. By the way there shouldn’t be so much of difference between the centre and the edge of the frame in a case of a telephoto lens of such a good quality.
At the end of the chapter, traditionally, we present crops of our resolution testing chart saved as JPEG files along with RAW files, used for the analysis above.
