Of course, my parents were pros, primarily working in 4x5, and they were slow to take 35mm seriously - the only 35mm we owned at first was a Stereo Realist for vacation slides. We got a Nikkorex F and 50/2 in 1963, with a lot more Nikon gear to follow shortly.
I had access to the studio Nikons and Nikkormats, and I had already owned a couple of "personal" Kodak roll film cameras and a Minox B submini by age 15.
But my first personal 35mm camera was a
Petri Color 35 I got in 1969. It was an excellent shooter that I used well into the 80s. It was so small that I often carried it in a belt case. Some 1970-1982 shots I took with that camera, all Tri-X in D-76 1:1, scans from 5x7 prints:
That Petri Color 35 was a great little camera, and it did a really fine job documenting my teens and twenties!
