The EOS R7 has one very big flaw.
Unlike almost all other Canon cameras in that price range, there is and will be no official grip from Canon.
The R7 is not tiny, but on the standard grip, there is no room for my pinky.
So I thought, well, I have to build one on my own.
I bought an old grip for the 50D (ad), which almost fits. (25$)
I removed all the electronics from it, because that won’t work, and removed the connector, which would normally fit into the battery compartment of the camera. I covered that with some kind of rubber.
To use the shutter and focus button from the grip, I soldered a 2.5mm Jack to the button, which is underneath the shutter button of the grip, and connected that via the external shutter port of the R7. So if I press the button it shortens ground and left and if I press a little bit more, it connects ground and right.
It’s like an external shutter, but internally.
The storage place of the grip can hold two LP-E6 (Ad – the ones I use) batteries, which are not connected to power at this stage of the build.
I screwed a grip pad on top of the grip, so that the R7 won’t move.
And that’s it. It works and it costs almost nothing.
Nice
Really appreciate your work. Thanks for it, I will give it a try.
I’m using back focus button configuration do you think it’s possible to add on the grip?
Thanks
Baz
Yes, you can use the back button. You just need to solder the wires to those.
You can also solder them to both without a problem.
Thanks Noel,
Find the way for the sutter but for the back button don’t find a solution . You think it’s possible to add it from the back button to the jack?
If I’m right the shutter is connect on the 2 last rings of the jack. For the focus don’t know? If you’ve an idea.
Shutter and Focus are on L+Ground or R+Ground. https://www.doc-diy.net/photo/remote_pinout/
Do u think it would work in an r10?
Or something similar, I was thinking on using some 3d printing for the 10mm that I need, but do u think it would be a good idea?
It would definitely work, but i’m not sure if it would be the same batterygrip model.
3d printing would work, but you would have to buy the buttons.
Thanks, , but on the 3d part I mean like the r7 is bigger than the r10, and I was thinking to use 3d printing to fill up the extra space on the grip, thanks for the tutorial
And where can I find a 2.5 mm Jack cabel?
You can buy the connector on Aliexpress and use any 3 core wire
Hello I am doing your steps and disassembled the handle but I do not know where I have to solder the wires can you help me?
Best you DM me on Instagram @_noelpicar
We just wanted to take a moment to acknowledge all the hard work and effort you’ve been putting in lately. Keep up the amazing job, you’re doing great!

Hi, I just bought a R7 and now also an additional BG-E2 (I’ll leave the old one on my 50D), love the shutter button idea, thank you for the hint.
Did you progress with the battery connection? You wrote that you store your LP-E6 in the BG-E2, did you modify the housing for that – it barely fits and I’m afraid I won’t be able to get them out again.
Hi Danny
Yes, I have finished the Project. I bought a cage for li-io batteries and connected two in serial to an adapter cable, which goes into a dummy battery. I can charge the grip via dummy battery in the normal canon LP-E6 charger.
If you want to use the LP-E6 batteries directly, you have remove some material from the grip.
On Aliexpress there are some LP-E6 plates, which you can place into the grip.
If you will do it my way, you can use some small 18650 and have some additional with you, if you need more battery.
Hope that will help you

Hi Noel,
The BG-E2 has arrived, I’ve opened it to take the extending parts off, which worked fine.
I have the battery cable still available, as I will link that to the dummy LP-E6 battery that goes into the R7.
* Now I wanted to further open the BG-E2 house, but somehow could not get the front and rear part from each other after removing all visible and reachable screws. What is the trick for that, do you recall? I would need this in order to connect the shutter button as you did.
* BTW, I’m 3D designing a cover plate for the part that was removed, in a way that it will hold the R7 in the battery-lid so that it will not rotate underneath the R7, and have a tiny border on the outside of the R7-grip. Once this is done, I can provide you one if you wish (but let me try to finish this first :-).
Hi
You have to remove the leather part. There are some more screws under there.
The 3D part sounds very nice!
