Between both C lenses and the CF/CFE the improvement is quite large.
Between the CF/CFE and the latest CFE/IF the improvemnet is quite
considerable.
The IF was developed with digital in mind. More resolution against an
increase in distortion.
Distortion is still quite low.
Questions like this do not make much sense.
It is not the optical differences but the way the camera has to be used
that is important to decide for a good 40 mm or an SWC.
