Super-Takumar
lenses featured an early form of lens coating (to prevent flare) and a more
sophisticated stopping-down mechanism. There was a switch on the lens to select
"Auto" or "Manual" modes. In manual mode, the lens would
always be in the selected aperture. In Auto mode, the lens would remain wide
open (at maximum aperture) until a pin on the rear of the lens was pushed in.
This pin would be automatically pushed in by the camera when the shutter was
tripped.
