Morning Gary et al,
Excellent news, very pleased you sorted out your manual focus control - was scratching my head trying to figure out what might me the problem
I'm the other way around ..... born a left hander, they tried to beat it out of me as a child but still one of the minority. Soldering with my right hand would be like soldering on the end of a ten foot pole.
With regard the DIN plugs. What I do is assemble the PCB first, then plug the DIN plugs into their respective sockets and then solder the wires on while they are plugged in. Having them plugged in provides a stable platform so you are not chasing them all over the bench. Also the socket & PCB acts as a heat sink so the plug body does not deform with the heat and obviously the socket holds all the pins in place. If you don't use too much heat the plug might even come out of the socket after soldering to
The suns out and I can see sky in the UK ...... miracle !
Clear skies,
Dave
