Protect the C-PL filter of your M75 75mm holder kit with this NiSi Protection Lens Cap. This cap attaches to the 67mm holder's main adapter ring when the kit's filter holder is removed. While in use, this lens cap can protect a circular polarizer filter installed on a separately available 72mm adapter ring while the adapter ring remains on the lens.
Note:
This lens cap is not compatible with the M1 70mm system.
