Changing things up a bit (no real reason to do so), I have, for the last several weeks, been leaving the M6s at home and begun carrying a single F3HP (sans MD4) with a 50mm F1.2 Ais Nikkor to shoot on the street (no camera bag, no other lenses). I stuff a couple of rolls of HP5 or Tri-X into my jacket pocket and go. The feeling is oddly liberating! While the Nikon will never match the Leica for quickness of focus, I am, by my own admission, getting fairly quick with the Type A screen that came with this particular camera (an $85.00 USD evilbay "win").
