I just came across this interesting page, discussing design
of various 85mm lenses produced by Asahi/Pentax in different mounts.

Interesting error regarding the A85/1.4:
"The "A" lens family offered aperture priority mode. This also was
offered a decade ago by companies like CANON, and 7 years earlier by
ZEISS (MM-lenses)."
The "A" lenses introduced SHUTTER-priority, not aperture priority
automation, and they weren't far behind Canon & Nikon in doing so, were
they?
They were well behind Nikon, which had a Shutter-priority version of the
F2 in 1974 or so. Not sure about Canon, and Contax was about the same
time as Pentax IIRC (MM lenses were a mid-80's development, It's the
Contax/Yashica mount that's 7 years older than KA)
