This cover allows the screwing of a filter at the LX7

Unfortunately, the camera has no lens cover LX7.
Only an antediluvian lid, which you must remove again and does not know where to put it.
The LX7 has a filter thread with which you can attach filters to the lens.
This cover allows the screwing of a filter under the lid.

The part is stuck, if you have screwed it right.
For this purpose it is necessary to remove the lens has a front ring and then unscrew the part in the same direction of rotation accordingly.
These are a type of bayonet lock without screw.
