Product Overview

The Pentax 49mm to 58mm Adapter Ring is built for shooters who want more options without weighing down the kit. Thread it onto any 49mm lens and you’re instantly able to run 58mm filters and hoods – handy if you’ve standardised your filters to one size or you’re running a mix of lenses. The cross‑thread‑resistant design and precision machining give you a snug, light‑tight fit, so you’re not fighting with stuck rings or dodgy threads in the field.

Made in Japan with a matte black finish, it keeps reflections down and blends in with the rest of your rig. Whether you’re lining up a long exposure on the coast, stacking ND and polarisers in the bush, or shooting close‑ups with a favourite prime, this genuine Pentax step‑up ring lets you carry fewer filters, swap gear faster, and stay focused on the shot instead of the hardware.
