A lens with a verified Ø55 mm ordinary front thread can accept a same-diameter screw-in filter as a mechanical candidate. Magnetic and holder systems need their own checks.

Ring direction
A step-up ring starts with the lens thread at 55 mm and presents a larger filter thread. A smaller front filter requires a step-down ring and may vignette.
What this does not prove
Thread size alone does not verify hood clearance, magnetic-system coupling, frame thickness or corner shading. Test at the widest focal length.
