No, I'm not referring to any of those. As I wrote, I'm referring to the Nikon AF-S NIKKOR 58mm f/1.4G, Sigma 50mm f/1.4 ART, ZEISS Otus 55mm f/1.4, and possibly a couple more released at the time. Note two of them have a stated focal length slightly longer than 50mm.The group of lenses you cite as uber-fifties were SLR lenses?
I think the new lenses in the family I'm talking about (RF 50/1.2, Nikon's new 50/1.8, Leica's new APO ASPH 50/2) are fresh, computer-generated designs that don't owe much if anything to previous generations of medium teles.
