Soviet-era Gadget vs Modern Camera
Today I'd like to share a mod I did to one of my Russian photography equipment, the Zenit Fotosnaiper! The mod essentially adapts the trigger-shutter system to work with my Sony A7 camera, so I can take pictures by pulling the trigger on the gun stock.
Here's a picture of the 300mm Fotosnaiper lens attached to the A7 via a m42 to Sony E-mount adapter as well as the gun stock.

How I did it / 改裝步驟
First I unscrewed the top plate on the gun stock, revealing the trigger mechanism.
I designed 3 parts with a CAD program that attached to the triggering mechanism which I printed with a 3D printer. These parts were then wrapped in copper foil with adhesive backing, to which I soldered wires from a shutter release cable. Here you can see the 3D-printed parts as white pieces and the copper foil.
The custom parts were designed so that when the trigger is pulled slightly, it triggers the half-pressed shutter action on the camera, which is usually set to auto-exposure and auto-focus, and in-camera body stabilization (which I don't have on the A7). When the trigger is pulled all the way, the red wire shorts to common and triggers the shutter.
Here's a photo of the assembled setup.
The other end of the cable release is plugged into the camera.
Testing it out! / 實際測試！
I took the modded Fotosnaiper to the streets and shot some everyday people scenes, here are the photos!
My hands were tired after walking around and taking those photos, and thus concluded my testing of the modded Fotosnaiper. It was a fun shooting with it, although the weight is quite heavy.
