Unfortunately I can not write anything positive about this product. In the first experiment the product was already damaged, it was no longer possible to him ever to be mounted on the camera. The substitute was then sent, has survived an hour in use (wedding photojournalism), has fallen and gone since then. Buy cheap buy twice called. The old wisdom has unfortunately been confirmed once again.
The original is unfortunately very expensive, but it fits much better and held for 1 year in heavy use after all.
