In addition one must gently but firmly turn the front about 2 mm wide ring on the lens with the LX-7.
So not the ring with the diaphragm values!
This is fixed with a bayonet-thread, not screwed.
Now screw on and completed the new cover.
Then open and close the lid on and off the camera in each case automatically.
The annoying fumbling with the standard cover finally has an end then.
The seller timetrends24 is also recommended unconditionally and receive it immediately.
Addendum:
Have now also have to realize that the cover after installation of FA1 no longer closes properly, if you have a filter installed.
So then place lid on it and then filter off and on it.
But he is still the first choice when you want to use the camera without the filter adapter.
But now there is a lid which closes completely allegedly also with filter.
When ordering so watch out if you need the version with or without a filter assembly.
