Re: The difference in quality.....

An f1.4, f2 or f2.8 lens is almost always optically better in the f3.5-5.6 range than slower f3.5-f5.6 lenses used wide open.

The fast lenses may, and often do, perform less well at their widest aperture than f3.5-5.6 zooms used wide open - but they can do things slower lenses cannot do.

Generally by f8-11 all lenses are optically excellent for sharpness and resolution, so stopped down to f8-11 there is little sharpness or resolution gain with a fast lens.

Practicing and thinking can do more for good photography than buying or consuming.
