The Gegenlichblende fits perfectly on my EF 50mm f / 1.8 II. It attaches securely and flush, could come through the light without gaps, with the lens. Since the objective of working out no recording has detents for aperture, the lens hood with an "adapter ring" is supplied for retrofitting these notches. This is simply screwed into the filter thread of the lens. The adapter ring itself has in turn inside a filter thread of the same dimensions of the lens. Thus filters can be used in spite of the adapter ring continues and the lens cap to be placed normally. Furthermore, can the panel eg for transport and put upside down on the lens.
Overall, it's sometimes a bit friemelig properly introduce the aperture in the catches and also it is possible that the adapter ring while turning the bezel is with bolt, if it is not screwed in tight enough. But I can imagine that these problems in the original part are also made me. Given the attractive price I like to see over it.
Shortly dispatch: Goods China also has been sent, the delivery was carried out smoothly and the package was given at the earliest possible receipt date already with me. A colleague has also appointed this panel, here was the package before the specified date with him.
