....one of those hokey-looking bulb shutter release hose deals? You know the
ones that use a pump of air to depress the shutter button. Are they legit to
any degree, ie... can you get a half depression then the full?

I used one to make this picture at a Riverside Raceway test day in
about 1984. I was getting ready to try for an effect with a wide-angle
lens on a camera sitting at the edge of the racing surface. You can
see some of the remote release and its spool on the ground. It didn't
work as well as I had hoped, but some of the photos are dramatic. I
was afraid to put the camera closer to the edge of the pavement.

The long tube was flexible enough that it was either full or none, as
I remember. I used a shorter tube to trigger a camera on a monopod
which I held high as I could above a crowd, to get a unique view. That
was on a Canon A1 with 24mm lens.

I'd say "Yes", legit, "Not easy", on the half-press.

Just curious: why aren't you using the electric remote control?

They worked when cameras used film and were mechanical. If you look
at an older SLR you'll see that the shutter button often had a
threaded hole for a shutter release.

Nowadays they're all electronic. Wireless, ethernet, internet, wired,
etc. No bulbs.

I still have mine. But none of my cameras can use it since it uses a
"standard" shutter release screw thread.
