Turns out that telephoto refers to a specific construction of a long-focal-length lens, i.e., one where the lens is physically shorter than the focal length.
Is there a generic term for referring to lenses of long focal length, while being agnostic as to their optical construction, other than just "long lens"? (Wikipedia claims there's not.)
Alternately, is this distinction simply pedantry and I should just call all long lenses telephoto?
