6. Distortion

You deal here with a fixed focal length lens with an angle of view of about 31 degrees. Such instruments shouldn’t have any distortion-related problems and indeed, the Kamlan manages to avoid them. You can notice just slight barrel distortion which value for JEPG files we determined as −0.76%. In the case of RAW files the result is, within the margin of error, the same, amounting to −0.78%. Of course you can try to pick holes and find lenses with the same or similar angles of view which corrected distortion in a perfect way. Still, with its modest 5 elements, the Kamlan did a good job anyway and, I suppose, a perfect distortion correction was positioned very low on the priority list of its optics constructors. Small wonder - if the distortion level of −0.8% meant a better correction of other optical aberrations it was the right decision to make.
