CineBloom 20% Diffusion Filter, 49mm

The CineBloom softens harsh digital detail, blooms highlights, and adds a cinematic glow without sacrificing sharpness or colour accuracy. CineBloom is Moment's custom diffusion recipe: a specific particle blend sandwiched between two layers of HD optical glass with a water-, grease-, and dirt-resistant coating. The 20% strength delivers a pronounced filmic softness straight out of camera.

Light & Strong

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

Works With Your Gear

CineBloom filters are compatible with standard camera lens thread sizes and the standard centre-pinch lens caps you already own. The filter screws on easily and stacks cleanly under ND or VND filters.

Choosing the Correct Filter Size

The filter thread size differs from the lens focal length. Check the front of your lens's outer ring where the lens cap attaches — it will show øxx, where xx is the filter thread size in millimetres. This filter requires a 49mm thread.
