Then the barrel distortion/color fringing can be corrected in the software (darktable, RawTherapee, etc...). Using a lens with a fixed focus (no zoom lens) greater than 100 mm is better. On the other hand, old photo prints mostly have barrel distortion/color fringing and in this case, it is about a flat object one is trying to digitise.
Please read well my post I did say "this lens might have too much barrel distortion/color fringing...", did the way I wrote let think that lenses don't have distortion/fringing?
