The Fujifilm company is not especially consistent when it comes to the distortion correction. In some lenses they correct it as it should be done and in some that aberration is left to be dealt with by the camera’s software. As a result it is invisible in JPEG files but in RAWs developed by independent software its level might be quite distinct. Of course the distortion correction and progressing from RAWs to JPEGs comes at a cost – the field of view has to be cropped. It creates a bit of a mess when it comes to the specifications - some producers state the size of the field of view for RAWs and some for already corrected JPEGs.

To be honest we didn’t know what to expect. The Fujinon XF 35 mm f/2R WR, tested by us before, corrected the distortion by using the software. The Fujinon XF 23 mm f/1.4 R, on the other hand, corrected it using its optics. One glance at photos below and you know that the slower model follows that example. The distortion amounts to practically zero both for JPEG and for RAW files developed by independent software. Officially we got +0.06% and +0.05% respectively so, within the margin of error, the distortion is zero. With such an angle of view it is a significant achievement and it deserves to be praised.
