When I shot crime scenes, I turned in the polices
Nikon, and shot Leica film cameras

Don’t know. Maybe an accident. I just got out of the hospital, after being in a coma of 11 days.
Sorry

Camera f-stops are based on the square root of 2. To go one stop slower, you multiply by 1.4 (the sqrt of 2, rounded off). To go one stop faster, you divide by 1.4.

Common “fast” 50mm lens is f/1.4. One stop faster=1.4 / 1.4=f/1.0. Going one more stop faster=1.0 / 1.4=f/0.7.

So, f/0.95 is so close to f/1 to be considered as f/1.

Why are fstops based on the square root of 2? Because to double the area of a circle you multiply it by the sqrt(2). When applied to the ratio of 1:f, you reverse the usage of division/multiplication.

I’m afraid you left me in my Circle of Confusion. LOL

1x1.4=1.4, 1.4x1.4=2, 2x1.4=2.8, 2.8x1.4=4, 4x1.4=5.6, 5.6x1.4=8, 8x1.4=11, 11x1.4=16... is this sequence starting to look familiar?

You are so right! We were screened and selected more than astronauts. If our wives bounced a check on base, we were pulled from pulling alerts. Our nuke was 9 megatons. A 1 meg would ignite dry leaves at 10 miles

Thank you Sir for your comments. I also spent 22 years, 7 months< 20 days in the USAF. Seven years underground in a Titan II ICBM. I was the guy who would “push the button”.
