Lenstip Fujinon XF18mmF1.4 Review: “It Breaks Resolution Records by a Very Healthy Margin with Only One Expected Flaw”


Fujinon XF18mmF1.4 – Simply Sensational

After getting the Gold Award by DPR, being immensely praised by ePHOTOzine and getting stellar customers reviews at B&H here, at AmazonUS here and at Adorama here, the Fujinon XF18mmF1.4 gets another fantastic review by lenstip.

Here is what they write about the resolution capabilities of this lens:

Let’s remind here that the best fixed focal length Fujifilm X lenses […] 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 – 85 lpmm and the best result so far belongs to the Viltrox AF 23 mm f/1.4 XF – that lens was able to get to 85.3 ±0.9 lpmm.

How does the Fujinon XF 18 mm f/1.4 R WR compare?

The performance of the Fujinon 1.4/18 in the frame centre is simply sensational as it is able to set new resolution records without breaking out into a sweat.

Already by f/1.4 the lens reaches a brilliant value of as much as 78.2 lpmm but it’s just a beginning. Practically every result in the aperture range from f/2.0 to f/4.0 would be a new resolution record but officially the highest resolution you get by f/2.8 and it amounts to 93.5 +\- 1.2 lpmm. It is right now the highest value optained on the Fujifilm X-T2 sensor. It is trully amazing that the old record is broken by over 8 lpmm!

In their conclusions they write:

After the test the situation is very clear. You get a long list of pros and just one flaw, and, additionally, it’s a flaw to be expected. The tested lens broke the latest resolution record and not just barely so but by a very healthy margin. In such a case we have no other choice than recommend the Fujinon XF 18 mm f/1.4 R LM WR wholeheartedly (even though its price, currently almost $1000, is rather high) and also award it our ‘Editors’ Choice’ badge.
