It might be marginally softer than my FL55/1.2 which I absolutely adore ... what Barney clearly doesn't have a clue about though is that these lenses were rarely made to be shot at max aperture ... wide open apertures were used as focusing aids in darkness but were expected to be stopped down prior to snapping.

Since the fastest normal lenses were for rangefinders (e.g. Canon 50mm f/0.95), this argument is weak. Canon may have introduced it's 55/1.2 for brighter focusing on the Pellix, but it did not matter as much for most cameras.

He could have shot a Konica AR 40/1.8 and found it soft at f1.8 too. You'll notice the next stop on that lens is miles away at f2.8 - the actual aperture most people were expected to actually use.

No, Konica just cheaped out by putting in only full clickstops. The 1/3 stop difference between f/1.8 and 2.0 was too small for an accurate clickstop.  Since all Konica bodies at the time of the 40mm had shutter-priority auto (where the lens could be more easily controlled to intermediate values), aperture ring half-stops were not considered critical.
