Here is the adaptation that I made for using the Photosniper with another camera than Zenit ES. Here with the Praktica B200, automatic aperture priority. This mounting is compatible with virtually all cameras with a cable release thread, provided that there is space enough between the base of the camera body and the butt for the passage of the cord.I remade the assembly (improved ). Here is the explanation:
Ingredients:A release cable(!)
This release cable comes from a double model. Advantage: it is adjustable.
As the inside cable was broken, it is a little too short. It will therefore be necessary to shorten the cord. One trick before cutting: one drop of super glue to prevent the sheath to unravel .
I also prepared: an hollowed out flash socket (from a Praktica MTL), and a lead screw (M4) having a hole of 1 mm in the axis (Thank you Denis).
While looking for something to make up the difference in diameter of the cord, I came across this spring. Impeccable, it adds flexibility to my assembly. The whole is glued using super-glue.
It will remain to fix the threaded rod on the small cable, after determining its exact location.
Disassembling the butt: remove the 8 screws I marked with red dots.
Here is the plate separated from the butt.
Remove the part for connecting the Zenit body, and the shutter-release finger.
And assemble in place the release cable. Testing remains to be done before gluing definitely the small cable into the threaded rod. When you press the trigger, the diaphragm must be closed first, then the light measurement should be done (automatic, aperture priority camera) before releasing the shutter. Once the bonding made, it may still be possible to play on the threaded rod, and the adjustable end of the cord.
And voila!Since there is little space between the base of the camera body and the outlet of the cord, my design has the advantage of being very flexible. No part of origin has been amended (the diameter of the flash socket corresponds exactly to the hole of the plate), the handle can be returned in a few minutes to its original state.
