Sony RX100 VII, RX100 VI Quick-Change Filter Holder (Part 2) by Lensmate

The filter/filter holder assembly (Part 2) bayonets onto the receiver for quick changes without having to thread the filter on and off.

Buy multiple Part 2's for all your commonly used filters.

Part 2, the actual Filter Holder, bayonets to Part 1 (which adheres to the end of the camera zoom lens) does nothing without Part 1,

Only the tiny receiver, Part 1, stays on the camera (it adds only 3mm to the depth of the camera).
The filter/filter holder assembly bayonets onto the receiver for quick changes without having to thread the filter on and off.
The filter holder is retained by a low tension locking system, so very little torque is applied to the lens barrel when attaching and detaching it.
