If you're going to do street, Eric, you need to do it with a small, preferably black camera. I used to love my Leica M4. Now my favorite is the Pen-F. You wrap the strap around your wrist and keep the camera in your hand. I learned to do that by trial and error. Later on, I saw a couple pictures of HCB with the same arrangement. Until virtually instant focusing came along I used to keep the focus set at about 15 feet, and aperture at f/8. That gave me enough DOF that I rarely had to change focus. You simply don't have time to screw around and shift gears if you're gonna grab something like the little girl or this. . . It's there and then it's gone. Usually you miss it, but when you catch it the catch makes up for all the misses.
