CineBloom 20% Diffusion Filter, 77mm Filter Thread

The Moment CineBloom gives your digital camera the look and feel of film. It softens harsh digital detail, blooms highlights, and adds a cinematic glow without sacrificing sharpness or colour accuracy.

CineBloom uses Moment's custom diffusion recipe — a specific particle blend sandwiched between two layers of HD optical glass. The frame is lightweight aluminium with a knurled grip, screws on easily, and stacks cleanly under ND or VND filters.

Light & Strong

Built from aerospace-grade aluminium, the CineBloom frame is strong without unnecessary weight. The precision-cut knurled edge gives a secure grip for fast removal, even when the filter is cold, wet, or stacked under another.

Works With Your Gear

CineBloom filters work with standard camera lens thread sizes and the standard centre pinch lens caps you already own.

Pick the Correct Filter Size

Filter thread size differs from lens focal length. The filter thread size for your lens is usually printed on the front of the outer ring where your lens cap attaches — it will appear as øxx, where xx is the size in millimetres.
