Damages Easily
I fitted this to a Sigma 500- 150. As a filter it works ok but I did bump the lens while in its padded case. The filter glass shattered, fortunately there was no damage to the lens itself but the filter mounting ring seems to have been bent meaning that it is impossible to unscrew it from the lens. If I ever do manage to unscrew it I will be replacing with something a bit more substantial.
