Are you OP? Or is this a thread hijack?
Either way, here's a quick lesson (from a relative beginner, so if anyone sees any mistakes, call me a nigger and correct me.)
If you don't know that much about shutter speeds or F stops, you probably don't know much about lenses and focal lengths and what designates a fast lens. So here's a "standard" lens.
50/1.8 (50 being 50mm focal length, 1.8 being f/1.8)
That means that the focal length of the lens is 50mm. The higher the focal length, the more zoom. Low focal lengths are wide angles. The f stop there designates how wide open the lens can be. The f stands for focal length, so the maximum width you can open the lens is whatever 50 divided by 1.8 is.
F stops. Alright, as a beginner, the most important thing to know is that the lower the f value, the shallower depth of field you get, allowing you to have one subject in focus with the others out. Also lower f values let in more light (since they're open wider) and so they require a faster shutter speed than a lens stopped down (meaning "closed," i suppose) to f/22.
Shutter speed is just that, the speed of the shutter. Lower f values need faster speeds to compensate for the large amount of light, and vice versa.
Hope this was at least a bit helpful.
