67-39mm Adapter Ring for 75mm System

This Urth adapter ring connects a 39mm lens thread to a 75mm square filter holder. It is designed for photographers who want to use square filters on lenses with a smaller diameter. The ring bridges the 67mm holder mount and the 39mm lens front.

Alloy construction with true threads

The adapter is made from a durable, lightweight alloy with a matte black anti-reflective finish. True threads provide a secure, snug fit between the lens and the filter holder. The standard sizing ensures compatibility with most 75mm square filter holder systems.

Upgrades from mismatched step-up rings

Replaces the need for stacking multiple step-up rings to reach the holder size. The direct 39mm to 67mm conversion reduces vignetting risk and light leaks. The jump is worth it when you regularly shoot with a 39mm lens on a 75mm filter system.

  • Connect 39mm lenses to 75mm filter holders
  • Lightweight alloy build keeps kit portable
  • Matte black finish reduces unwanted reflections
  • True threads ensure secure, repeatable mounting
