Voigtlander Nokton 35 mm f/1.2 X / Z

4. Image resolution

The resolution test of the Voigtlander Nokton 35 mm f/1.2 X 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 records for this sensor amount to about 85 lpmm and higher; so far such results have been achieved by the following lenses: the Viltrox AF 23 mm f/1.4 XF (85.3 ±0.9 lpmm) and the Fujinon XF 18 mm f/1.4 R WR (93.5 ±0.9 lpmm).

Now let's check how the Nokton 35 mm f/1.2 X compares in the frame centre and on its edge – an appropriate graph you can see below.

Voigtlander Nokton 35 mm f/1.2 X / Z - Image resolution

I admit that, looking at the combination of this lens's physical dimensions and its aperture fastness, I was very curious about its resolution graph. As you see there are no big surprises.

In the frame centre, by f/1.2 and f/1.4, images are of weak quality. They become decent near f/1.8 and then they improve very fast as you stop down the lens. By f/2.8 you see a very good level of almost 70 lpmm and by f/4.0 the tested Nokton is able to achieve an excellent result, exceeding 80 lpmm.

The performance on the edge of the frame is interesting indeed. With such small dimensions of the tested lens I didn't expect any fireworks; unfortunately the reality was even harsher. You can enjoy images of more or less decent quality only on stopping down the lens to near f/8-f/11. It is definitely not a performance you would expect from a good quality standard lens.

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.
