BAYONET FORCE BOOSTER FOR ADD-ON LENS

An add-on lens assembly (400) supporting an add-on lens (402) for a camera (100), comprising a rotatable lock ring (408) having a cam pin (410) that navigates along a slot (432) of a cam (430) such that when the lock ring (408) is rotated, the cam pin (410) causes the cam (430) to translate axially...

Zusammenfassung:	An add-on lens assembly (400) supporting an add-on lens (402) for a camera (100), comprising a rotatable lock ring (408) having a cam pin (410) that navigates along a slot (432) of a cam (430) such that when the lock ring (408) is rotated, the cam pin (410) causes the cam (430) to translate axially so as to compress a spring (440) toward a pusher (414) so as to increase the attachment force between the lens assembly and the camera. The increased force between the add-on lens assembly and the camera provides additional support for large or heavy add-on lens assemblies.
