Sorry, I haven't been keeping up with the forum. It sounds like your shutter is stuck open, usually caused by a sticky brake pad. The mirror won't come down until the second curtain finishes its run and trips it. It's something that needs to be attended to in a full CLA. The problem with Contax cameras is parts are getting scarce, and if it happens to be an electronic fault, there's not much that can be done about it.
Thanks for your Answer, ridgeblue99, much appreciated. The Problem, Issue seems to be...the Mirror is permanently flipped up, i 1st thought, it's missing from inside the Mirrorbox, but it's flipped up, all the way..and doesn't come down, no matter how you put, set the Mirror Flip Switch.
The mech. Shutter (1/50s Speed) isn't working, and i can't see any Titanium Shutter, when i open the Film Back, i can see only a Help Shutter Cloth, but not the Metal Titanium one, like on my fully functional RTS II.
It's a shame, this RTS II looks & feels like new...even subtle better Condition, then my working Copy.
The Electronics seem to be somewhat working, when i attach a Lens, Metering works as expected. But not the Shutters...so here might lie a Problem...
