Urth 67-46mm Adapter Ring for 75mm Square Filter Holder

67–46mm Adapter Ring for 75mm Holder

This precision-engineered adapter ring connects a 67mm lens thread to a 46mm interface, enabling use with a 75mm square filter holder. It is built for photographers who want to run a single filter system across multiple lens diameters without carrying separate holders. Durable alloy construction and true threads ensure a secure, repeatable fit during frequent changes. The matte black anti-reflective finish helps prevent glare from degrading image quality.

Threaded adapter limits with square systems

The ring bridges a specific 67mm front thread to the 46mm mount required by the 75mm holder, so it only works with lenses that present a 67mm filter thread. Lenses with smaller or larger threads, or those lacking front threads entirely, cannot use this adapter. The fixed 46mm interface means the holder cannot be rotated independently once the ring is seated, which may restrict orientation of graduated filters. Vignetting can appear at wide focal lengths because the holder extends beyond the lens barrel.

Replaces individual step-up rings

Instead of buying separate step-up rings for every lens or purchasing multiple square-holder kits, this single adapter lets the 75mm holder serve all 67mm-threaded lenses in the kit. The upgrade is worthwhile when a photographer already owns the 75mm holder and regularly shoots with 67mm threads, eliminating redundant hardware. It does not help shooters who need to adapt non-67mm lenses or who prefer circular screw-in filters for speed.
