4. Image resolution

The resolution test of the Fujinon XF 14 mm f/2.8 R was based on RAW files from the Fujifilm X-E1 camera. Those files were developed with the dcraw program (with a 3-pass X-trans filter algorithm) and analyzed with the help of the Imatest package.

Let’s remind here that the best fixed-focal lenses, tested that way, can reach results of 70-72 lpmm and the decency level is set near 40-41 lpmm. Let’s check how the tested lens compares here.

We don’t hesitate to call the results you get in the frame centre sensational. Already at the maximum relative aperture you get images with a great resolution level because the MTFs increase to almost 69 lpmm. The lens reaches the peak of its possibilities by f/4.0-5.6 where it goes as high as 72 lpmm. On further stopping down the diffraction makes itself felt and the MTFs start to decrease.

When it comes to the frame edge our feelings are mixed. On the one hand even at the maximum relative aperture the lens can provide useful images (with its MTFs reaching over 42 lpmm) – so there are no reasons to complain. Still we are worried by the fact that the resolution values improve very slowly on stopping down so there is a huge difference between the frame centre and the edge which amounts to over 20 lpmm.

At the end we present some crops taken from JPEG files saved along RAW files we used for the analysis above.
