1966, MC I, 5 grp / 6 elm, 435g, MFD = 1.2m, 7 iris blades
filter size = ∅62mm (rather rare among Minolta lenses)
$1,000 @2014 (silly money)

(This is a well made lens, must have been very expensive
to produce. That is why it had short production life, also
I've heard its AF version (different optics) has a short life.
And one doublet of the lens seems very difficult to make,
which reduces the production yield consequently IMHO.)
