These are the cheap materials to start with to make an improvement and strong shutter release adapter. The long screw and square and round nuts are only cost USD 0.22. The small copper tripod nut I collect from my old spoiled tripod. I remove the hard plastic that covered around it and look like that.
The round nut is grinded to reshape so that two sides created on the nut. This is made due to nut too big and hinder from my Sigma to place on the camera adapter. The copper tripod nut is hammer in into round nut. Before you hammer the nut in, you have to screw in other short or long screw into Copper nut and hammer onto the end of short or long screw to drive in the Copper/tripod nut. This way nothing will spoil. The work is completed as in the picture.
Then as you can see some works are completed ie grinding on nut and sharp ends of square nut are grinded a bit bluntly and this nut is used to lock the long screw on to the round nut so that the screw stand firmly after you have screwed in the long screw to the tripod nut which is already inside the round nut.
Yeaaa it is ready to use now. Simple and strong. Fix it anywhere on the camera adapter!!!
Detail is shown.
The lens protrusion of this camera - CANON DIGITAL IXUS 980 IS - is short, and since the camera is so near to the eyepiece of the spotting scope, the Shutter Release Adapter is placed at the back on the camera adapter.
While here the Sigma lens protrude much longer and camera body is put at the back end on the camera adapter. Shutter Release Adapter is here at front on the camera adapter.
Ordinary tools are to be used for any works. The triangle ruler here is only use for checking the 90 degree vertically right of the Shutter Release Adapter.
Ahh these tools are always come together. You always need Vice when you grind.
After almost a day improving my shutter release adapter and able to successfully complete. My test is this White-collared Kingfisher or Mangrove Kingfisher where just infront my house. Good Shutter Release Adapter and no shake from it at all.
