Linhof Profi Jr Tripod was obtained over 50 years ago and it was not used so often because of the construction on the adjustable center pole construction. Fixed vertically tight and elevator adjustment were fond of by myself, I was disciplined by those ideas. The ideas controlled me unconsciously to select the suitable tripod. But, the revolutional mechanical device came to me recently by chance.
Quick Release System by Velbon Co. brought me several changes of fundamental and basic idea. Eliminating bothering of complicated tightening and losing mounting screw and the critical risk to fall down the main equipment while operation is desirable.
Linhof Profi tiltable center pole mechanism and Quick Release system, both of them contribute to eliminate the troublesomes in the actual operation leading to safety and relieve. Collet type engineering plastic ball with 3 slits provides enough working angle movement and the single tightening thumb screw fixes the movement in 3 dimensions at the same time. Also, this screw knob adjusts precisely the rate of slipping resistor of the ball movement. In addition, center pole plays a part of Panning long handle while adjusting including hight movement together. Consequently, this thumb screw knob fixes all the adjusting element with single action.
It goes without writing here for the enthusiasts that the Center of Gravity should be supported Physically for smooth adjusting, the pic shows Slik Supporting Plate is invited for the purpose. Tokina 400mm old lens is active even now.
