Unless they include wet mounting and spot illumination — dedicated film scanners will suffer from a degree of flare.
Additionally these devices also suffer from distortion because the original is *never* mounted flat.
I’ll guarantee that, although in focus, all scanners that use film holders produce distorted images. You’ll only notice if you send a neg or transparency off for drum scanning and then overlay one scan on another. Your 6x7cm neg will be a number of mm short across the film width because the natural bow in the film is not corrected by the film holder.
Drum mounted originals stay flat — they need to as the depth of field is only a handful of microns :-(
