I own a Canon R8 mirrorless camera. I also have the BR-51 Canon remote shutter trigger. I am trying to find a motion-activated trigger that I can use to photograph wildlife that is compatible with this camera, either branded by Canon or another company. It looks like Vivitar made one, but it doesn't seem to be available anymore. Has anyone found a solution to this? Thanks, Jeff

What do you use then to trigger it? And the only connecting cable I see is the Nero for sub mini Canon cameras? What kind of cable do you use to connect the MIOPS unit to the camera shutter trigger port?

As mentioned, my primary use of the MIOPS trigger is for photographing lightning. For the birds at my feeders I use the motion feature through my phones camera. Since most of my cameras are upper end, I use the 3 pin port on the front of my cameras to connect the MIOPS trigger. The R8 uses a 2.5mm sub-mini connector, but I'm not sure what the MIOPS end uses, although it looks like the 2.5mm.
B&H has a MIOPS trigger that comes with a Vello brand 2,5mm sub-mini connector, so that may be the cable you need, or some other brand. At the time I bought mine, MIOPS offered different cables in the package, but it seems like they have discontinued offering that. You may want to contact B&H to confirm which cable you need.

OK. Thanks for the explanation. It doesn't explain any of this on the camera specs on website (I guess I'd have to download the manual). And I assume the original MIOPS Smart+ camera along with phone app will do this (it's not an updated version). Have you tried it from a distance? I have a zoom and may want to be 30-50 feet away from my subject. Can you zoom in with your camera to get a smaller area that's farther away?
I appreciate your being patient and responding to all of my questions!

Also, how do you connect your phone camera to the MIOPS device? Will it work with an iphone?

Bluetooth. So if your phone supports it [Bluetooth] you can "pair" it with the MIOPS trigger. Once paired, you can use the MIOPS app to control the trigger and access all the functions and settings. You can even do AEB to capture HDR shots, and also time-lapse.
I don't use it a lot, but it's there when I need it 🙂

I promise this will be my last question! Have you tried it from a distance if you're using a zoom lens? Can you zoom in your phone camera on the subject? (see my previous note). Jeff.

And which cable do you use to connect the MIOPS to your R5?

If you order from MIOPS, you select the cable that matches your camera. The cable that I use on my R5 (I & II), R6 (I & II), and my 5D mark IV have a C3 (3-pin) female connector, so the cable provided by MIOPS has their 2.5mm (TRS/TRRS) connector that plugs into the trigger and a C3 connector for my camera.
This cable will not work on the R8 as it takes a 2.5mm connector.

I've never tried letting my phone trigger the MIOPS/camera while using a long lens. I typically use EOSU 3 to monitor my feeders via live view. I also have a 30' USB cable for my 5D IV. It doesn't work on my R cameras so I use WiFi for them unless I'm within 10'.
I'm able to set in my house and remotely take shots of the birds at my feeder... Yes, I get lazy sometimes 🙂

One last thing. Is the phone camera trigger mode reliable with your short lens? Are there a lot of false triggers or a lot of misses? I realize that you don't use it with a long lens. Does your phone camera shut down if not used for a while?
