While I own a three body (M6x2, M4P), five lens (28,35,50,75,90) Leica system for candid/street photography, I have found over the years that probably most of my street work has been shot with either the 28 or the 50. The beauty of the rangefinders is that they allow me to work in close to my subjects, unhindered and almost always unnoticed. If I am carrying a bag, I load one body with E100G and the second with one of Tri-X/HP-5 (for most of my daylight shooting) and then often switch to Ilford's Delta 3200 for existing light work (an amazing film!).
