I have tried several of Hood with 43mm thread for the LX 100, but all have vignetting so worried for dark corners in the picture because they have towered into the picture box. I did not really want to spend so much money on a lens hood, but on a recommendation in the Lumix forum back, I bought the lens hood LH-XV on Amazon. Panel as cover are made of metal and very valuable to the LUMIX LX 100 there is absolutely no vignetting! The cover is designed at the inner edge with black velvet to avoid scratching the lens hood and to be placed almost noiselessly.
Therefore, there is a buy recommendation from me!
Only a little cheaper it could be, therefore, a star deduction. The panel is manufactured in China and sold under the name of JJC LH-XV Hood for Leica Vario X digital camera (replacing Lens Hood Leica 18774). The Lens Hood LEICA 18774 costs about 100 euros. This seems also the explanation for the high price of the replica realtiv to be here.
