Speaking of Leica...
Going back to around 2008, I finally ran into a photographer who was sort of street shooter legend in San Francisco, shooting photos there for 30+ years. His name is Vladimir (went by Vlad, and originally from Ukraine long ago), and he shot exclusively with Leica M2 cams. He had at least eight of them. He was a very interesting character and a little eccentric; but in a nice way.
He named all of his M2s after vintage Disney characters; Mickey, Minnie, Goofy, etc. And one after a race car driver he admired, Fangio. And labeled the the back of each a Disney metal sticker.
Wanting to save weight for each of his cameras, he dissembled them and de-chromed the body shells down to brass in a tank of acid using a car battery and a lead plate. I’m guessing that may have saved a tenth of an ounce of weight. He also made his own grips from washed-up driftwood from SF beaches.
I started running in to him a lot of SF, so we eventually traded photos in the mail as postcards. His were printed in his darkroom on nice paper. Because he was vehemently anti-digital, he would address them to me as Pixel Slave, Pixel Junkie, Digital Evans, etc. He’d also write “Film is History, Pixels are Disneyland.” Cracked me up! His best move was sending me an 8x10 silver print folded in thirds so it would fit in a business envelope.
