4. Image resolution

The resolution test of the Fujinon XC 35 mm f/2 was based on RAW files from the Fujifilm X-T2. Then the files were developped with the dcraw program (with the 3-pass X-trans algorithm filter) and analyzed with the help of Imatest package.

Let's remind here that the best fixed focal length Fujifilm X lenses, tested that way, are able to reach as high as 80 lpmm and the decency level is set near 44-45 lpmm. The resolution record for this sensor amounts to about 83 lpmm. Now let's see how the Fujinon XC 35 mm f/2 compares in the frame centre and on its edge – the appropriate graph you can see below.

Taking into account the price-point of this lens and its target audience, the results in the frame centre can only be praised. Already at the maximum relative aperture MTFs exceed 60 lpmm so the lens can offer you a very good image quality. On stopping down the situation even improves, reaching its peak by f/4.0 and f/5.6 where you can observe results of 75-76 lpmm. It's true that these numbers are hardly record-breaking but you really shouldn't complain.

A comparison to the more expensive XF series brother is also interesting. That lens fared better in the centre, its resolution increased faster and the peak of its performance was reached by f/4.0 where, on the less densely packed X-E1 sensor, the Fujinon had a result of 77.3 lpmm. Its higher than the maximum result of the XC model reached on the X-T2 sensor.

The results on the edge of the frame are another curiosity. Here, in the wide range of apertures from f/2.0 to f/8.0, you see practically the same values – within the margin of error they stay on a level of 60 lpmm or so. It seems to be a tad better performance than in the case of the more expensive XF brother as its resolution decreased on stopping down - we saw results of about 50 lpmm, but you have to remember they were reached on a less densely packed sensor. Overall you can say that both instruments fare equally well in this category but the cheaper XC model seems to be slightly better.

At the end of this part of our test, traditionally, we present crops taken from photos of our resolution testing chart which were saved in the JPEG format along with RAW files, used for the analysis above.
