$2.00 Wired Release from Found Objects....

Just spent some time testing.

The remote actually worked today, but does not do focus.  That's fine.  I can focus first, then make the shot with release without touching the camera.

The cable.  It can do either focus or shutter release, but not both.  But when the camera shutter button is used or touched, the cable release would stop working.  No response at all.

Must be some contact problems...
