Originally posted by blacklite I'm not quite sure how you can be sold something that is "brand agnostic" and believe it. I'd suggest there's a huge chance that using a connector type adaptor (so not adapting protocol and/or electrical specification, just physical connector) to allow you to connect your magic "works with everything" box may damage your camera.
The scheme of a remote shutter is pretty simple: a mass, a pin for half press and a pin for full press.
My intervalometer just maps these three to a female jack, in a standardized way.
Then, you need an adapter that maps the contacts in the jack to the pins in the camera connector, following the pin map of your brand.
I've had it for 5 or 6 years and used in some different cameras without any issues.
In fact, Hama has a whole system, called DDCSystem, with remote shutters, timers, wireless shutters and IR shutters. They use this jack-to-connector system, but sadly they don't make a Ricoh (or Pentax) adapter.
Yes, I know I could buy a remote for the GR from JJC, after all the camera has a built-in intervalometer and just need the remote shutter. But I like to reuse my items if I can
