Can anybody explain to me how the "soft touch" release button is made?
I thought it was just something you screw on the release button to have a larger surface to press your finger on. In which sense is it "softer"?
Or does it have some sort of probe activating the shutter like the one in a cable release? In that case maybe it is softer because there is a soft spring and no need to win the resistance of the camera shutter release which is probably a bit stiffer. Is it that?
Soft touch is merely a large diameter button that increases the area your fingertip contacts. It screws into the cable release threads.
