what do seasoned street shooters use for making photographs? What's your primary street-shooting system?
Primary system: Leica M

My go-to street photography kit: Leica M4-P body with my Summicron 28mm f/2 ASPH lens and my Sekonic L-508 meter.

Film: Kodak Tri-X or Fuji Pro 400H if I want to work in color, both of which I develop at home.
