So I have these 2 lenses in 210 mm for 4*5:

A f5.6 210 mm Symmar (chrome on the outside), single coated, in an older Synchro Compur (old shutter speed range), single coated

A f9 G-Claron 210 mm mounted in a Polaroid Copal 1, I guess single coated.

The Claron is about half the weight of the Symmar, but more than a stop slower.

When enlarging negatives to 40*50 cm (most frequent size) or 50*60 (max in my tiny darkroom) would there be discernible differences (yes I will run that test.. ..) ?


Best,

Cor
