Interesting compilation, Andre.  I have always thought that lens
makers in general (and not just Pentax) tend to use a little bit of,
er, um, well, shall we say, "imagination" in "stretching" the specs
just a bit, as shown by most published lens tests I've ever seen.
That is to say...

1.  Apertures are generally a tad less generous (i., a wee bit
narrower) than advertised.

2.  Wide-angle lenses are generally not quite as wide as advertised.

3.  Telephoto lenses are generally not quite as long as advertised.

4.  Zoom lenses generally have focal length ranges less generous
(i., narrower) than advertised (and generally at both ends of the
zoom range, too).

This happens so often that it is almost comical...
