I'm close to getting the GR-V1 grip to work with Canon C70 and wanted to share some findings and get some advice!
I pre-ordered the C70 with the intent of using on my shoulder on occasion and having on-grip controls. It would be a massive flaw if this camera were unable to do so, as that means it simply can't compete as a documentary camera.
I'd love anyone's assistance helping me find a cable/adapter to work from the 3.5mm Canon C handgrips to the 2.5mm remote terminal. I'm fairly certain this will work based on the below findings.
FS5 and FS7 Grips
Connected via LANC cable, both of these handles are recognized by the camera and the joystick functions with up/down/left/right and select. The record and other buttons do not work, which is expected because they are mapped differently. But it shows that the remote link's capable of receiving multiple signals.
Do not work, because audio cables don't provide either enough power or consistent signal. (Or maybe I just can't plug them in all the way)
Cameo Gear Grip
This thing is ugly and buttons are a bit flimsy but it works via hirose to lanc cable. I've tested this as well. Iris and button mapping work. These are somewhat hard to find as they are entering EOL.
This, of course is the natural choice to use. I've purchased it and am looking to connect it to the C70. Any help in selecting a cable (or cable+adapter) to make this happen?!
Attached are a few photos
The Canon 3.5mm grip connection on the GR-V1 (C-series grip). The C70 only has 2.5mm remote in.
This cameo gear grip works but it's really not intuitive and no longer supported by manufacturer.
(Yes, excuse the tripod ball.)
Lastly here are some of the cables I have tried. I was advised to use 3.5mm to 2.5mm audio adapters but they either do not fir or do not work with the GR-V1
Any thoughts on where to find a cable or combination of cables to get the GR-V1 grip working on c70? Thanks all!

I'm still trying to get the GR-V1 (or any canon grip) to work with the C70. This is a tremendous oversight on Canon's part imo.
After cutting a Canon grip extension, it appears the Canon cable has 6 cables, a standard lanc has 3. I've ordered a 2.5mm TRRS cable which may work, and will also test all combinations of connecting it with a 3-cable lanc.
If anyone has any knowledge on the below, do let me know which might connect to which to at least get partial functionality out of this grip.
