I guess I was thinking of an automatic diaphragm stopping down without the extra buttons or levers. When shooting with my 1964 SV (in 1964) and ST 55 f/1.8 I never had to stop the lens down to make an exposure because it was automatic. I seem to remember the older cameras needing to be stopped down manually before exposure which darkened the viewfinder. Of course I may have gotten the C Nile Virus!

If we're going to '64, both the original Nikon F and Canonflex had been on the market for several years, and I believe both had quick, auto close-open diaphragms from their introduction. My first Pentax, also my first 35mm camera, was a Pentax "S" followed by either a Heiland or Honeywell Pentax which had the pin operated close-open diaphragm system that remained standard on numerous 42mm lens mount cameras for many years.

The Minolta SR-2 introduced in 1958 featured a fully automatic stop-down diaphragm.

Surely the next flagship will be a K2 not K4 if Pentax stay with this series naming conventions.

According to Wikipedia, Exacta introduced the external diaphragm mechanism in 1954, and the first internally operated, close/re-open diaphragm mechanism was introduced on the ill-fated Zunow camera of 1958. Truth is, the original Nikon F really established the 35mm SLR as THE camera design.

Apart from being disgusting, that camera would also be the first one to which a lot of people will be allergic to.
Thank you for existing.
