Fujifilm Fujinon XF 56 mm f/1.2 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 80 lpmm and the decency level is situated near 44-45 lpmm. Record results on this sensor are near 85 lpmm and higher; so far the best resolution we measured while testing 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 Fujinon XF 56 mm f/1.2 R WR compares in the frame centre and on its edges – an appropriate graph can be found below.

The new Fujinon by f/2.8 is able to exceed a level of 90 lpmm – it sticks out immediately and it allows us to refresh our list of record-breaking lenses. The official result amounts to 92.8 ± 1.1 lpmm so, within the margin of error, is in accordance with the record resolution, that of 93.5 ± 0.9 lpmm.
The performance near the maximum relative aperture is equally impressive: by f/1.2 you see a sensational result of 75.3 lpmm and it gets improved to 78.3 lpmm on stopping down the aperture to f/1.4.
We don't have any doubts that the performance of the Fujinon 1.2/56 WR in the frame centre is outstanding. It's interesting that the new model fares here noticeably better than the faster and bigger Fujinon XF 50 mm f/1.0 R WR. It's not a direct comparison, though, because the test of the older lens was performed with the help of the X-E1, with a higher resolution detector. Still, the older model barely exceeded the decency level at the maximum relative aperture so it seems its successor is distinctly sharper.
The performance on the edge of the frame can be described only in superlatives as well. It's true that the results are lower but it's only because you compare them to excellent resolution in the centre. Even by f/1.2 you get here a value of over 62 lpmm so exceeding the decency level by almost 20 lpmm. On stopping down the aperture you are able to exceed 70 lpmm and near f/4.0 the lens approaches even 80 lpmm – a round of applause!
