As an old street photographer, I'm accustomed to zone focusing so I'm always ready to shoot. Waiting for my Panasonic lens to autofocus has cost me lots of great shots. So I switched to my old Leica Summaron 35mm/2.8 and Panasonic adapter. I love it! I do miss how light the Panasonic 20mm lens is compared to the Leica lens. And, of course, the 35mm Leica functions as a 70mm on the GF1 and GX1. Would it be unreasonable to ask for a Panasonic or Olympus brand Micro 4/3 manual lens so I could zone focus!?
