Just read an article on a camera blog that concerned me. Several Hasselblad users said it is very difficult to use the Hasselblad hand held at slower shutter speeds. They indicated that one will not get a sharp image using anything under 125th of a second. I want to use my 500CM for available light candids. I have a 50mm, 80mm and 150mm lens. Does anyone have experience shooting hand held candids with the 80mm? If so, what is the slowest shutter speed you were able to use? I am sure I would be able to use the 50mm at slower speeds, but am concerned about the 150mm. In a few days, I will experiment using a newspaper as a target and try hand holding all these lenses at about 10 feet to see the sharpness of each lens at each speed. This will be for black and white images and I will try the various fast films as well. I really love using a tripod for everything, but candids would require one to be less obvious.
