Step-Up Adapter 55mm to 77mm

The ProOPTIC step-up adapter ring connects a 55mm lens thread to a 77mm filter thread, letting photographers use larger filters on smaller lenses. It is built for shooters who want to standardise on one filter size across multiple lenses without buying duplicate glass.

Replacing individual filter sets

Instead of purchasing separate 55mm and 77mm versions of every polariser, ND or special-effects filter, this single ring lets the 77mm filter cover both thread sizes. The jump is worth it when you already own or plan to buy 77mm filters and want to use them on a 55mm lens immediately.

Comfortable range and limits

The ring comfortably handles any 77mm filter — circular polarisers, neutral density, UV or creative effects — on a 55mm front thread. It runs out when a lens has a different thread diameter, when a filter larger than 77mm is required, or when a step-down direction is needed instead.

Questions about this item

Will the 55mm thread on my lens accept the adapter ring without vignetting?

The ring is machined to sit flush on a 55mm front thread, adding only the thin wall thickness needed to reach the 77mm outer diameter, so vignetting is minimal on most lenses.

How do I attach the ring so the 77mm filter stays aligned?

Screw the adapter onto the 55mm lens threads until snug, then thread the 77mm filter onto the adapter — avoid cross-threading by starting both connections by hand before tightening.

When should I replace the adapter ring if the threads wear?

Replace it when the 55mm or 77mm threads no longer grip securely, allowing the filter to rotate freely or loosen during shooting.
