4. Image resolution

The resolution test of the Fujinon XF 60 mm f/2.4 R Macro was based on RAW files from the Fujifilm X-Pro1. It’s worth reminding here that, when it comes to that sensor, the decency level is situated near 40 lpmm. The Fujinon 1.4/35 got as high as 65 lpmm and the 2/18 model reached 62 lpmm. Let’s check how the tested lens compares here.

Macro lenses are often one of the sharpest devices in a given system. Small wonder our expectations, concerning the Fujinon 2.4/60, were high. Still they were also tempered by that compromise design of the tested lens, intending to give a macro and a portrait lens out of the same instrument. If you put too much pressure on universal properties, you often have to lower the quality of an optical product. Perhaps the Fujinon 2.4/60 was a victim of such a policy ; anyway its maximum results are rather comparable to those of a ‘pancake’ than to those of an outstanding system ‘prime’, which should exceed the level of 65 lpmm. To defend the tested lens a bit you can state two things: firstly, there are no resolution records here but the value of 62 lpmm is still excellent. Secondly we have here a sensational performance at the maximum relative aperture, where the lens gets to a very high value of 58 lpmm. Such a result doesn’t differ almost at all from the maximum values so in the frame centre you almost don’t have to stop the aperture down at all to improve the image quality.

The edge of the frame also doesn’t give you reasons to complain. The area near the maximum relative aperture allows you to get sharp images – the MTF50 function values, measured by us, reached 49 lpmm. It is interesting that a slight stopping down not especially helps when it comes to the image quality. Fortunately when you use the f/5.6 relative aperture the lens gets to a very good level of 54 lpmm.

At the end of this chapter we present crops of our resolution testing chart, taken from JPEG files; they were saved along RAW files, used for the analysis above.
