When one uses old film cameras for art-making there is an implicit understanding that 50+ year old equipment will likely require an intervention of sorts. My Rolleiflex 3.5F Xenotar is with Paul Ebel getting a CLA and will likely not be back before the end of summer. My Polaroid Spectra Pro is down for the count and is exposing about one print in five (It will have to go to Polaroid Originals for service), My Polaroid Macro 5 is not working, and last evening I had to do a mechanical intervention on my Polaroid SLR 680, as the electronic shutter button was not working (cleaned the electrical contacts inside the camera with a pencil eraser and all is well now). On the positive side, once serviced with a clean, lube, and adjust, most of these grand old ladies work admirably for many years.
I have a cadre of artist friends on Flickr that over the past few years, have been regulars at communicating about our work, methods, equipment, and travels. While we don't all share the same language (online translators work fine for the most part), we do share a love of film and mechanical cameras which touts a language of its own. This brotherhood and sisterhood of sorts is inspiring, as well as educational. There are many more film opportunities outside of the USA. Japan reigns as the location for the vast majority of mint film cameras by far. Thus far, I have found Japanese sellers on Ebay to be exceptionally honest. Here is a website worth following, if for nothing more than for the "In Your Bag" series.
“What ultimately got me through was my single-minded determination, voiced aloud to myself and recorded in my diary, to discover the causes of my blindness and never to repeat them. Fearlessly pursuing insight was my badge of honor, my route back to self-respect.”
