Hi,Yes, their first PPSLR was introduced in 1960. I will add that that was Kowa(flex). Then the Kowa(flex) E in 1961, introducing auto metering. Thanks!
Kowa made one even earlier than this Kowa H, there seems to be one from 1959 (?) called Kowaflex. There is one on ebay now.
The Konica Autoreflex of 1968 was the first automatic system to measure light through the lens, TTL. I will rewrite things to make this more clear. Thank you!
Savoyflex was first, but not regarded as a very useful system. Then Kowa H in 1963. Then Kiev Avtomat in '64. But Konica got all the credit from 1965.....
