far from the "best enlarging lens on earth."

The best enlarging lenses (and copy lenses) on earth
are designed as flat field and optimized for certain magnification ranges.

A modern 50 or 35 mm Summicron "may" perform very well
as an enlarging lens
at a given focus distance and aperture;
though I doubt it would outperform the best modern, apo enlarging lenses;
aperture for aperture.
