A larger mass will be more effective at isolating vibration.

The mass makes absolutely no difference. It is the natural frequency of the object that matters.

I actually think you are right.

Does the natural frequency of an object not change with a change in its mass? Surely different dimensions change the natural frequency.

When the frequency of the vibration in Hertz coincides with the natural frequency of the object, the oscillation ( shake) tends towards infinity.

If you know how to do it, one can get a structure weighing many tons to vibrate by swaying on your feet.

Soldiers marching across a bridge.

However the mass helps with camera shake as it requires more effort to move the object.
