When I think Sun Sniper (normal version without metal wire) put into operation, I thought that the supplied button is fully capable of resisting selbsständiges unscrewing. The rubber disc conveys really tight fit and safety. As someone has probably reckoned without the host. A D700 with battery grip and the corresponding zoom lens give a weight with which such "eye" must be done only once. Conclusion: has fully opened the thing "thankfully" not. Equal first. I did it very well screwed together very tightly. The forces that constantly draw while wearing on the ring and the frequent draw forth when using the camera offensichtich cause a noticeable change of the seat of the original screw. With ball bearing mounted camera screw this issue is resolved. I think that the producers deliberately even better anchoring, but offers an extra. But these are considerations which lead me to any deduction.
