all of these focal lengths out of whack is due to aps-c cropping.
Just
another good reason for Pentax to put out a FF dslr body!
But they went to some trouble to create an entire lineup of DA lenses
with adjusted focal lengths instead. So 16-50 ~= old 24-70, 50-135 ~=
old 70-200, DA*55 is the de facto portrait lens, etc.
For those many of us starting out with a blank slate on APS-C, the
Pentax bodies together with the DA and DA* lineup makes perfect sense.
It's just those legacy lenses that don't fit so well. :-)

I reckon one of the few benefits of not having taken up photography
until well into the digital age is that I don't know any of this stuff.

also means you can go about the business of making pictures without
all the teeth-gnashing over what is and isn't.
Precisely. It really helps that I don't have any idea what the FOV of
a 50mm is "supposed" to be.
-- Walt
The FOV of a 50mm is short telephoto on either 35mm film or APS-C
digital, it's just more of a Telephoto on APS-C. The "normal" lens by
convention on 35mm would be about 42.5mm the diagonal of the film,
"normal" for APS-C would be about 29mm so, you know, you can do what you
want. Mini cams have been breaking the rules since Barnack invented the
Leica.
