6. Distortion

The Fujifilm X system lacks consequence when it comes to the distortion correction. Some lenses’ optical construction manages it beautifully, without any help from a camera’s software; in some lenses the correction of that aberration is almost completely delegated to the programmers. The Fujinon 10-24 mm belongs to that second category.

As long as you deal with JPEG files, the distortion won’t disturb you. At 10,17 and 24 mm it amounts to −0.88%, +0.57% and 0.69% respectively. These are low values, meaning it’s difficult to notice any deformations in real life photos.

The RAW files are quite another story. At the focal lengths, mentioned above, the distortion was respectively: −4.62%, +1.53% and +2.15%. While you can try to understand huge barrel distortion at the ultra-wide angle (but still many rivals manage to correct it quite efficiently) I admit I have great difficulties with accepting values higher than 2% at the maximum focal length.

When you give up correcting one of the basic optical aberrations you get much wider room of manoeuvre with the rest of them. Unfortunately, in the case of the tested lens I haven’t noticed any practical usage of those possibilities: neither the sharpness on the edge nor the chromatic aberration level were quite as low as you would expect from a top-of-the-range piece of equipment.
