NiSi Canon 11-24mm 77mm to 180mm Filter Holder Adapter Ring camera filter

Canon 11-24mm Lens Adapter

This adapter ring connects the Canon 11-24mm lens with its 77mm filter thread to a NiSi 180mm filter holder system. It enables landscape and architecture photographers to use large-format square or rectangular filters on this ultra-wide zoom. The ring is a dedicated mechanical interface for that specific lens and holder combination.

77mm Thread to 180mm Holder Limit

The adapter bridges a 77mm front thread to a 180mm holder, so it only works with that exact lens diameter and holder size. It cannot be used on lenses with different thread pitches or on smaller filter systems. Vignetting may appear at the 11mm focal length depending on the filter thickness and holder configuration. No step-up or step-down function is provided.

Anodized Aluminium Build Quality

The ring is machined from anodized aluminium alloy with a plastic casing component for the holder mount. The metal construction resists corrosion and wear during frequent filter changes in the field. The precise threading ensures a secure, light-tight fit between lens and holder. Its low profile minimises the risk of vignetting at the wide end.
