When To Use Which Lens and Why

Lenses are each used for different purposes.  Really, what this means is that each lens has a different focal length or low aperture capability that will produce very different results when used.

Much more than you think it would!  Here is a FABULOUS ARTICLE I came across in making this principle very apparent, with incredible photo illustrations of the concept.  A must read.  Enjoy.
