Has anyone used this non-Canon, less expensive hood?
"GSI Super Quality Lens Hood for CANON EF 100mm f/2.8 Macro USM, and EF 100mm f/2.8 Macro Lenses - Functions Exactly as the Canon ET-67, Provides Protection from Light and Impact"
It is available on the Amuzon site. I wondered how well it works, fits, and if it is really identical to the Canon hood.
