Viltrox AF 35 mm f/1.7 Air
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).
Let's check how the Viltrox AF 35 mm f/1.7 Air compares here – its results in the frame centre and on the edge of the frame presents a graph below.

Like in case of the 15 mm focal length model you get here sensational results reaching over 90 lpmm, brushing against resolution records. By f/2.8 the tested lens gets a brilliant result, that of 91.8 lpmm. If you add to it a value of over 70 lpmm at the maximum relative aperture you can only clap and cheer.
A graph below shows that the Viltrox AF 35 mm f/1.7 Air compares very favourably to its rivals. Let's remind here that its price tag amounts to less than 800 PLN. The slower Fujinon XC 35 mm f/2 costs roughly the same, but the faster Fujinon XF 33 mm f/1.4 means spending $950.
In case of 15 and 25 mm models we got sensational results in the frame centre but at the expense of the edges. When it comes to the Viltrox 1.7/35 the situation is slightly different because here also the edges fare very well. It's enough to point at the result of almost 61 mm at the maximum relative aperture and 66-68 lpmm you reach on stopping down the aperture to f/2.8-f/5.6.
Once again you can compare the tested lens to both Fujinon instruments- we present it in a form of a graph below.
It's clear that the Viltrox fares the best, with momentarily a very pronounced advantage. If you take into account its affordable price, physical dimensions, and parameters, it becomes truly impressive.
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.
