#3. "RE: Standard f-Stops"
In response to In response to 2

Lenses (or most of them, anyway) are not limited to full-stop steps in aperture. An f/1.8 lens is two-thirds of a stop slower than an f/1.4 lens.

The difference between lenses of f/1.8 and f/1.4 is not really in the physical diaphragm itself.

As the aperture opening gets larger, lenses tend to need a more complex (and hence more costly) optical design in order to deliver good image quality when used wide open.
