Introduction: Canon EOS600D & Fotosnaiper
I've built on a previous instructable and shown how to adapt a remote to fire using the actual trigger mechanism on the fotosnaiper. This is a lead on from this https://www.instructables.com/id/non-destructive-photosniper-on-a-canon/. This was done using a canon EOS600D, fotosnaiper with corresponding tele lens and an RS-60E3 remote (http://www.amazon.co.uk/Canon-Remote-Switch-RS-60-E3/dp/B00007EE78/ref=sr_1_1?ie=UTF8&qid=1445610263&sr=8-1&keywords=rs-60e3)
Step 1: Adapting the Fotosnaiper
As you can probably tell the mount has a piece of metal at the end of the arm for securing the original zentih camera in. For nearly all cases this needs to be remove before mounting a modern digital camera onto the setup. Luckily there's a step by step guide to doing this here; https://www.instructables.com/id/non-destructive-photosniper-on-a-canon/ so follow that for removal of this piece of metal.
Step 2: Adapting the Remote Shooting Control
The aim is to have the trigger fire the actual camera as opposed to other mounting options. This can be done relatively easily. Firstly place the remote disconnected from the camera place it in the "locked" position (push the button down and slide up).
Step 3: Adaptation Contd
Next remove the two screws at the back of the remote. This will take the cover off. Inside you'll see a 3 piece metal switch. This either breaks or closes the circuit causing the camera to fire. In the locked position you can lift the longest piece of metal (closest to you) and this will cause the camera to take a picture, providing the remote is in the locked position.
Step 4: Mounting the Remote on the Fotosnaiper
On the tele lens provided with the snaiper you'll see a lever with an arm protruding from it. Align the remote so that this little arm can be slid underneath the previously mentioned lever. The arm is metallic so it will conduct electricity and break or close the circuit. Then selotape the remote to the side of the sniper so that the lever breaks and closes the circuit when the trigger is pulled. See the video and image above.
Step 5: Things to Note
You might need to keep pressure on the selotape to hold it in place, this shouldn't be an issue for right handed people as your thumb will be in this area anyways. Also this should work in a release fashion i.e. pulling the trigger will prime the camera and releasing it will take a picture.
That's all there is to it. It'd be great to see if anyone has a better way of doing this, perhaps a 3d printed mount for the remote? Also with the back removed the remote could be very susceptible to water damage so this mightn't be the best option in wet weather.
