Soviet-era Gadget vs Modern Camera
當蘇聯怪器具搭上現代相機

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.

今天來跟各位分享一個相機器材改裝過程，被改器具是蘇聯時代製造的Zenit Fotosnaiper。主要改造的部分是將槍扳機的聯動轉換成數位相機的快門觸發，使得扣扳機就能達到拍照的功能。

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.

以下照片是 Fotosnaiper 配的 300mm 鏡頭透過轉接頭接到 Sony A7 機身上及槍托。

How I did it / 改裝步驟

First I unscrewed the top plate on the gun stock, revealing the trigger mechanism.

首先把槍托上的蓋板拆下來，露出裏頭扳機結構。

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.

接著透過電腦3D軟體我設計了三個小零件，畫完後用3D列印機打印出來。這些零件貼上了含背膠的銅箔之後各別焊接至一條快門觸發線之三條線。以下照片看的出白色為3D列印的零件及貼附住的銅箔。

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.

這些小零件的作用使得當我將扳機微壓時會觸發相機的自動曝光計算/自動對焦/放手震（因爲老鏡頭的關係所以沒有自動對焦及防手震。當我將扳機扣到底時則會觸發快門，拍下照片。

Here's a photo of the assembled setup.

以下是整個組起來的樣子。

The other end of the cable release is plugged into the camera.

快門觸發線的另一端接到相機上。

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!

我把改造後的Fotosnaiper帶到街上拍攝了一些日常街景，以下是照片！

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.

拍完這些照片我手也累了，改造測試就到此告一段落！這玩意兒還挺好玩的，只是無法持續用，手會累。
