While I stand by my likes & dislikes regarding lenses, said ls & ds are really immaterial to this thread - because, as has been pointed out, the only real impediment to my photography is between my ears.
I've been looking a some Kodachromes I made in the early '70s, using a Kodak 35rf with an uncoated f:3.5 lens. My lightmeter then was a late '30s bakelite Weston.
No modern lens or technology would improve on those slides, or on any photograph I have made in the intervening (almost) fifty years.
P.s. still have that Kodak.
