ABOUT TRIPOD, HEAD AND VIBRATION

MARCH 2005

PAGE 12 OF 15

VIBRATION AMPLITUDE [um]

camera system under test was so loosely assem- bled that it seemed just like driving an old car on an unpaved road. Top quality tripods and heads become useless. It is so easy to ruin your setup. You only need to have one minor element that is not proper. A slightly touch of your lens will result like this.

at no cost. This is one of my conclusions. Try your- self to be a sniper if your camera has no MLU function, if you get your tripod free. There should be a situation that makes your effort worthwhile. However, don’t persuade anyone that one can beat a regular tripod unless you have a third leg.

Windy Condition

Wind is often the main source of vibration in outdoor photography. A really sturdy tripod sys- tem is required. In a windy condition, the ball head is better than the 3 way head because the wind pressure would be smaller. Screw type tri- pod leg is better than lever type. Main structure on top also has to be designed aerodynamically.

Above is another case which is not for the worst case; this is a regular situation. This signal was measured at the end of Nikon 80-400mm VR lens mounted on F100 camera. A customer who vi- sited the Markins office willingly took part in our experiment and did operate his equipment on tripod very carefully. We can learn from this ex- perience that we need to have a little time be- fore actually taking shot to minimize vibrations during equipment manipulation. We can also use a self timer for the same purpose. However, it will not work if the self timer does mirror up just before the shutter release. The mirror should be at up position far before the shutter action.

Try to run 100m in 11 seconds.

It occurred to me that a human body has so much potential that it might be possible to hold a camera very stable. If we practice, if we keep in good shape, we can hold it better than some cheap tripod. I mean something we get virtually
