In one of many films about JFK this past week,
there definitely was a Nikon-F with Photomic head, not TTL.
I thought i must be dreaming..
sure they came later..
Shooting downwards is difficult, Not Impossible.
When i was a young, had an air rifle.
I was an amazing shot.
Once many years later at a shooting range,
a friend gave me his Beretta to shoot some targets.
I was to walk away and turn when he shouted.
I saw a line of bottles about 50 feet away.
I was on a rise, the targets below.
I shot as fast as possible.
I hit 8 out of 10.
Oswald had a scope, was a Marine "Sniper".
The why will never be answered.
