Cool! Especially this:

I'm surprised this isn't used more often.


It's used more often that you might think, and you'll find examples of
both tilt (tipping the lens up or down) and swing (turning it left or
right) as with the train or ST:TNG still if you know what to look for.
Tilt is often used for purely creative effects or extreme depth of field
for long-distance shots, swing is mostly used for keeping two characters
(or whatever) in sharp focus like this is really the only usage I've
noticed for swing. Swing is a pretty good solution for scenarios where
the director wants a deep depth of field but lighting conditions mean
high ISOs and/or wide apertures.

The limiting factor is more the camera used and what mount options are
available as realistically, you need Canon EF or Nikon F mount, although
there are a few other options for TS-E/PC lenses. Now that DSLR lenses
are being used more for broadcast video the options for tilt/shift
lenses have gone up and I expect to see much more usage.

In the days of plate and cut-film cameras, most such cameras had the
ability to employ a number of such adjustments. Only the more
expensive 'technical' cameras offered the full range. See for example
