This adapter is designed to work on the Fuji X100 with a 49mm filter

The Cap for the X100 Glass and Mk 4 hoods will also fit on this adapter.

The original Fuji cap fits as well.

We also have a 49mm Haze filter which can been seen in the product photos, this is the same glass as on the x100 glass Haze lens hood.

 This ring will fit all of the cameras in the X100 line up including the X70.

This adapter ring along with a 49mm filter will weather seal your x100.
