f-stop

Pushing the aperture or the F-stop down as low as possible allows the most light in, and he suggests setting the ISO as high as possible without adding grain to the image.

It was like, “Well, what kind of an f-stop would you use on this? Blah, blah, blah.”

“With manual shutter and f-stop, it was a real camera with which to learn and could take great photos. The Argus was built like a tank. I saw one that had a big dent in the corner after being dropped on a concrete driveway and still took perfect photos.”

Spin this dial to adjust f-stop or hold down the small button on the right side of the camera while spinning the dial to adjust shutter speed.

I would have to pull the screen out first, then dial in the ISO on a touchscreen, then adjust my hand to reach the shutter and f-stop dial on the front all before I could snap the shot.
