This sale is for a boxed, brand new Fuji GX680 Bellows Lens Hood Adapter Ring 100. This adapter ring allows the later 100mm size GX680 bellows lens hoods to be fitted to earlier 82mm filter size lenses. Most of the 100mm hoods coming out of Japan do not have this ring and cannot be fitted to the smaller size lenses without this adapter.
This adapter ring is new so has no signs of use.
More Fuji GX680 kit available, including hoods with the 82mm ring – if you cannot see what you want then just ask.
