I bought this lens hood for my Panasonic LUMIX LX100. It fits hervoragend the lens, but unfortunately the aperture vignetting at wide angle at 24mm focal length (equivalent to KB). It was not until about 32 mm focal length it has completely disappeared from the corners of the image. See Photo! The front diameter of the outer edge 56 mm, important for z. B. a Aufsteckdeckel.
Nevertheless, 4 stars, because the lens hood is processed with value and clean. 1 star deduction, because I would have wished that the description refers to suitable focal lengths.
