I would be interested to know how the 50/1.4 S tests on correctly functioning equipment. The brownish tint of the lens gives me pause.
For the tint of your lens, others have noted this also. One of the recommended cures is to place the lens without caps on a window sill in a south facing window for a few days (a week?) where sunlight can shine through the lens, and the coloration seems to go away. This also aflicted a couple of my Minolta AUTO ROKKOR-PF 1:1.4 f=58mm lenses. Some Asahi-Pentax Takumar lenses also show this effect.

When they ask you; "How many Mega Pixels you got in your camera?"
just tell them; "I use activated silver bromide crystals tor my image storage media."
