What it is and who it's for
The Urth 67mm Main Adapter connects a lens with a 67mm thread to a 75mm square filter holder. It suits photographers who want to use square filters on lenses of that specific diameter. Builders using other thread sizes cannot attach this ring without an additional step-up or step-down ring.
The deciding specification
The adapter accepts a 67mm front thread and mates with a 75mm square filter holder system. Magnalium construction provides a rigid, lightweight mount that resists cross-threading. The true-thread design ensures the ring screws on cleanly every time, so the filter holder sits flush and parallel to the sensor plane.
What the coating and environmental pledge change
A matte black finish reduces internal reflections that can lower contrast when shooting into bright light. Each purchase funds the planting of five trees in deforested areas, adding a reforestation benefit to the optical accessory. No software, pouches or additional hardware are bundled with this adapter ring.

Questions about this item
What does the 67mm size mean when I attach this adapter to my lens?
The 67mm diameter matches the filter thread on your lens, letting the adapter screw on securely so the 75mm square filter holder can be mounted in front of the glass.
How does the thread standard affect mounting speed and compatibility?
True threads on the 67mm ring engage cleanly with standard lens threads, giving quick, jam-free attachment to most 75mm square filter holders.
What physical clearance does the magnalium ring need to sit flush on the lens?
The low-profile magnalium construction adds minimal depth, so it clears most lens barrels and hoods without vignetting when the 75mm holder is locked on.
