Yes, I am told may do not. I wonder why not, given that I use a cable relase
with film cameras al lthe time. It's a pity such things are not standardised and
documented.
Not a universal standard, but many SLRs use a 2.5mm jack plug that
simply shorts some contacts. I remember when I got my first camera that
supported electrical/electronic shutter release. There's nothing wrong
with a cable release when you're manually operating the camera next to
you, but the only common and reliable way to do it from any distance was
an air release. I had one, good for about 50 feet. The electrical
release, though, meant I could easily do all sorts of things previously
only available with fairly complex and expensive gadgetry. It was
trivial to make something that fired the camera in response to a sound,
a flash of light, or the interruption of a light beam, or a periodic
timer. Now virtually all SLRs, most bridge cameras, and many compacts
support electronic and IR triggering, and the cost of the trigger device
is about the same as a decent cable release. Somewhat less, if you
already have an iPaq, iPhone, or Android phone and only count the
software cost.
