3.Taking advantage of a tripod or a monopod: The difference between sharp pictures and shots blurred by camera shake is one second away. When using a 100mm lens, 1/100 sec., is the limitation for holding the camera steady. A faster shutter speed is strongly recommend- ed for shooting with a medium format camera, since this unit is larger and heavier than a 35mm camera. If a shutter speed slower than 1/60 second is required when using a 65mm, a tripod or monopod is highly recommended. Using a monopod effectively to stop camera vibration requires a certain knack. Adjust the elevation of the monopod so that the camera viewfinder rests at eye level. Hold the camera against your forehead and form a tripod with the monopod and your legs to stop the swaying motion of the camera.

Note: When mounting the camera on the tripod, use a cable release to increase stability of the unit.
