K&F Concept 49–67 mm Brass Step-Up Ring + 3 Cleaning Cloths

The K&F Concept 49–67 mm brass step-up ring lets you fit filters, lens hoods and other 67 mm accessories to a lens with a 49 mm filter thread. You can use one set of larger filters on smaller lenses too, without buying filters for every diameter. Three cleaning cloths are included.

Brass ring, 49 → 67 mm

The ring is CNC-machined from durable, flexible brass, so it screws on smoothly, does not deform and resists corrosion. It fits the lens and filter threads precisely, keeps out stray light and preserves image quality – images stay sharp and the focus plane remains flat.

How to find your thread size

The filter thread diameter is printed inside the lens cap or on the lens barrel. The ring suits all lenses with a 49 mm thread and accessories with a 67 mm thread – filters, lens hoods, ring flashes and lens converters.

Cleaning cloths

The ring comes with three vacuum-packed cleaning cloths. They are gentle, dust-free and clean optics without the risk of secondary contamination.
