SmallRig CO-F1 Clip-On VND Filter for iPhone 18 Pro / 18 Pro Max 6877

The SmallRig CO-F1 6877 clip-on VND filter cuts light steplessly from ND2 to ND32, so you can hold a slower shutter and keep natural motion blur even in harsh sun. A silicone clip attaches it to an iPhone 18 Pro or 18 Pro Max with no extra mounting base.

The SmallRig CO-F1 6877 clip-on filter is a variable neutral density filter for the iPhone 18 Pro and iPhone 18 Pro Max. Turning the front ring runs steplessly through ND2 to ND32, so you set exactly as much light reduction as the scene needs — no swapping glass, no jumps between fixed values. That lets you hold a slower shutter even in harsh midday sun, so pedestrians, traffic and flowing water keep a natural motion blur instead of looking stuttery. The control is one-handed and works while recording, so exposure can be trimmed without stopping the take. A flexible silicone clip holds the filter on the phone without an extra mounting base, goes on in seconds and works with most cases that leave a large enough cutout around the lens backplate. At 50 mm across and just under 13 grams it is an accessory you actually carry, and the dual-layer build keeps MagSafe access clear. Check the shape and size of your case cutout.
