Good read - and true, like all Stella´s stories. But speed is not everything. Without proper coatings flare is even bigger problem. Many pre-war superspeed lenses had a minimum aperture of something like f:8 because flare made them unusable beyond that - seems like the diaphragm reflects so much light back that multicoating makes a lot of difference.

The SMC-K 50mm F1.2 talk reminded me of a good Dante Stella article on the subject of fast lenses at:

After a lengthy discussion of technical issues related to transmission vs aperture, Dante ends the article with the following quote:
"But admit it, superspeed lenses are cool"
Boy that's more stoked with supposition than his normal rants, hasn't the guy ever heard of lens hoods?
