...re: discrete/size
Yes, good points. However my personal goal is to carry the camera discretely and casually, but use it openly (for the most part). That's not everybody's trip!
I'm trying to develop the self-confidence to walk up to people and ask if I may photograph them, getting their address and promising them a print. FAR from "street photography" or "candid." I'm not interested in "irony" or coincidence, I'm interested in learning how to make and depict these relationships...Avedon did it with an 8X10, so maybe I really shouldn't worry about an extra inch of Ultron 😀
For my purposes a Canon G6 might be perfect, as might any number of point-shoots with film, some with equally good optics, except that a Leica with optical finder is evidently (my experience) interesting/impressive to subjects, it sets me apart from the guys with the huge DSLRs and cellphone cameras :angel:
The formality of the photo relationships I'm after is central to the equation.
On Sunday I visited a growers market with my P and Nokton. All the usual photo ops, but I ignored them. I fell into a discussion with a man who raises "heritage" (antique) tomatoes and other veggies, sells them as plants and builds small greenhouses...a former Marine and early Vietnam vet, complete with boonie hat and Corps badges. So here's this interesting guy...and I did buy tomato plants from him...and we did talk about my Canon P, which he did recognize as a fine and unique camera...but I chose to keep the game more in his court, letting him talk about himself and about plants...and we did a little light jousting about Vietnam (I was a very active Vietnam war resister when he was over there, risking death). I chose not to photograph him, but I will call him back in a week, ask to visit, ask to make his photo when I get there. A guy my age, certainly my personal equal, a man with lots of personal mileage and soul. I want to show him more respect than simply snapping him as a character at a flea market. Therefore camera selection plays a role. I might even use my little Century Graphic (a little bigger than P with Ultron 😎 as easy to carry as a Canon F1 😎 )
