Have the diffuser bought before a wedding in order to make more beautiful, more evenly-lit images. First first: the diffuser fits well and does not shake, as well described it before. The wedding photos are very good. Especially with the many white (wedding dress, ...) it is important to have a more diffuse lighting, so not everything will be totally eclipsed. So definitely recommended. Have nevertheless bought after the wedding the original diffuser of Metz, since with it the mirror is automatically moved to the wide angle position. But had no opportunity to test the difference.
