This hood is wider than previous Squarehood lens hoods. The hood screws straight onto any adapter for the Ricoh GR III and GR IIIX.
Both of the native Ricoh GA-2 and the GA-1 adapters are compatible as well as the NISI adapter.
The hood screws into the female 49mm thread on the adapter, and a 49mm filter can also be attached to the hood.
The hood comes with a rubber cap and a tool for alignment.
