Brass step-up ring for 72mm to 77mm filter threads

This brass adapter lets photographers mount 77mm threaded filters onto lenses with a 72mm standard filter thread. It suits anyone who wants to use a larger filter system without replacing existing glass.

Brass alloy frame with knurled grip

The durable brass alloy frame prevents the binding and jamming common with softer metals. Knurled sides give a secure grip for quick attachment and removal, while the anti-reflective treatment on the inner surface cuts internal reflections during long exposures.

Passive design adds no power draw or noise

As a purely mechanical ring it introduces no electronic load, fan noise or thermal output. The matte black finish helps minimise stray light without affecting the lens’s own thermal behaviour.

  • Use 77mm filters on 72mm lenses
  • Brass alloy frame resists binding and jamming
  • Knurled edges give secure grip when mounting
  • Internal anti-reflective treatment cuts flare on long exposures

Questions about this item

How does the brass frame prevent jamming when stepping from 72mm to 77mm threads?

The brass alloy resists deformation better than aluminium, so the male 72mm and female 77mm threads stay aligned during repeated mounting and removal.

What physical clearance does the ring add between the lens barrel and a 77mm filter?

The slim brass frame adds only a few millimetres of thickness, keeping the 77mm filter close to the front element without vignetting on most lenses.

Which side of the ring attaches to the lens and which accepts the filter?

Screw the 72mm male thread onto the lens first, then thread the 77mm filter into the female side; the knurled edge stays accessible for removal.
