2/3" Support, Ruggedized Distortionless Macro Lenses VS-MCA Series
The hexagonal design allows the use of a torque wrench. Torque can be controlled by using a torque wrench and screws can always be tightened with the same force. * If the torque wrench does not enter, there are two incisions in the edge of the lens so that it can be fixed with a crab eye wrench.
Easy tightening with a torque wrench
