Auto Open and Close Lens Cap Protector for Leica D-LUX 8 D-LUX (Typ 109) D-LUX 7 Panasonic Lumix L10 LX100 II (DC-LX100M2) DMC-LX100 Replace DMW-LFAC1 Automatic Lens Cap,Fit Filter Thickness Below 8mm

This! I just got my L10 (stoked!) and as soon as I put a protective UV filter on I hated how the regular lens cap fit/looked. Primed a JJC one from Amazon, and to my surprise it not only fits with the filter installed, it rotated and clicked into place surprisingly well. TBD on the quality / ymmv. I am also probably gonna pay the eBay tax to order an OEM Panasonic one from Japan, but this should (hopefully) tide me over in the meantime.
