Now we are actually getting into advertising claims. The tests I have seen show
the Vivitar 19mm as actually being 21mm. In fact, many lenes are only within
(10% or so) to their nominal focal lengths.

DJE said, among many other things:
Wide angles wider than 28mm are rare. 20mm was either too expensive to
build, too hard to design, or too extreme to sell in sufficient volume
because almost nobody but the manufacturers made them. Only Sigma makes
one, and that is recent. ...
A Vivitar 19mm f/3.8 also exists.
