The most common performance metric listed on spec sheets for tripods is the weight rating.  This is supposed to represent approximately how much weight the manufacturer believes the tripod can reasonably support.  The problem is there is no standard definition as to what ‘reasonably support’ means.  Tripod manufacturers use different test methodologies, none of which […]

In order to properly calculate damping times, we need to know the moment of inertia (MOI) for the camera and support system as a whole.  In the previous two posts, we have measured the MOI for tripods and ball heads.  The final piece is what we discuss here, the MOI for the camera and lens […]
