Hi all,
Sounds like other models may have an occasional vibration similar to my Pilot. I've pretty much narrowed down the source to be a slight amount of backlash in the bushings that the cheeseplate/quick release plate attach to, inside the tubes at the sides of the stage. There are four connection points, and I think there is a slight amount of play there. When I clamp my hand around the plate and the tube, the vibration is much reduced.
Anybody else seen this and dealt with it simply? Is this something I should contact Tiffen about? TIA
