i just read a bit about the retrofocus lens (design or attachment??) that is used with SLR camera lenses to enable the use with some wide angle lenses while allowing enough room behind the lens for the mirror to move.
but. i am wondering. is this retrofocus thing a lens design or a lens attachment ??? or both?
and if it is an attachment, can it be used somewhat like a teleconverter, except to serve the opposite purpose on a 'normal focal length' lens? (an inverted teleconverter????)... making the normal focal length lens more of a wide angle(??)
(thank you)
