Mat 124G Unwilling Shutter Release (01)
Yashica Mat 124G. Japanese 6x6 TLR.
This camera had the problem that the Shutter Release Button was unable to trigger the Copal shutter when focussed at infinity.
First step in opening the front is removing the Collar of the Release Button (see green arrow).
I read (too late) in one of Rick Olesons Technotes that's best to first lock the Release Button by turning the Locking Lever to the red L position (see red arrow).
There are 2 pinholes in the Collar so you need a special pinfaced spanner for that. I used an adapted circlip spanner. Be sure that you use a well fitting tool otherwise it will slip and degrace the Collars face. Turn ccw.
