Sirius, thanks!
Dr C, I'm almost embarrassed to name the cameras here where you guys have the good equipment, but the spotmatic I've had forever and is in who know what repair, it was for slides back in the day. The rangefinder is a retina iia which is just delightful to hold, in known good shape and replaced a broken canonet. Neither viewfinder, I'll admit, is optimal, but I was more inclined to chalk it up to user error and upgrade when I have the skills to push the equipment. (if you really want to give me a reason to hunt down a contax, though...)
The metaphysical advice applies regardless, thank god it's fun!
