Manfrotto Sympla MVA513WK Long Lens Support System
The system is configured out of many SYMPLA components. Two of them in particular -- the SYMPLA Body Support and the SYMPLA Lens Support -- are what reduce vibrations. Both height-adjustable and rubber-coated, one presses up against the underside of the mounted camera and the other similarly against the far end of the attached lens. The camera and lens are thus stabilized and vibrations caused from focusing or pressing buttons are very highly reduced.
