Always shoot my C330's on a tripod (slow film Junkie). Recently, did some hand held portraits for friends. Humbling experience. Missed focus on half my shots as I juggled wind-on, change hold, focus-shoot, change hold, etc. Now I need to do some more portraits (for folks who saw the last ones), AND, I want to shoot some street stuff. Well, once upon a time they used speedgraphics and MPP's, so why not my Mamiya?? I know there are left hand grips, and flash grips, and pistol grips. Who has used any of them? Do they help? Any best avoided?? (P.S.- Yes, I know, use a 35mm rangefinder, but humour me.)
