I hate to admit, but I either never have known or totally forgot having known...

What does the "F" in f-stop stand for?

or the "f"in f/8?

Thanks in advance for the remedial photo lesson.

Going by //www.paragon-press.com/lens/lenchart.htm it says that the "f" is the focal length. In that case, it is possible to have a f/1? I don't think I've ever heard of one anyways...

4700 bucks gets you F/1.0

The f in f-stop is the "focal ratio", the ratio of the focal length of the lens to the diameter of the aperture.

And yes, there have been f1.0 lenses.

Stanley Kubrick used an f0.7 lens in making one of his movies.
