SmallRig Attachable VND Filter ND2-ND32 (1-5 Stop) 67mm 4581

FAQs:

Is this filter only for phones, or can it be used on cameras as well?

It is designed mainly for mobile filmmaking, particularly with SmallRig mobile cages that support a 67mm magnetic adapter ring. SmallRig also includes a threaded adapter ring, allowing the filter to be used on camera lenses with a 67mm filter thread. That makes it more flexible than a phone-only filter, especially if you move between mobile and compact camera setups. The fitting method just depends on whether you are using the magnetic cage system or the threaded ring.

What does the 1 to 5 stop range actually do?

A 1 to 5 stop variable ND filter provides a practical range for controlling exposure without changing shutter speed or aperture as aggressively. For video, that usually means you can keep shutter speed at more natural settings in brighter conditions, which helps motion look less harsh. It can also help when you want to keep the aperture more open for a shallower depth of field. The range suits daylight and mixed-light shooting without pushing into very heavy ND territory.

Do the hard stops make a noticeable difference?

Yes, especially on a variable ND designed for quick use. The hard stops at ND2 and ND32 give you defined endpoints, so you are less likely to overshoot the usable range when adjusting exposure. That makes the operation feel more controlled, particularly when you are working quickly on a phone rig or changing lights, which forces constant adjustments. It is a small handling detail, but one that makes the filter more predictable in practice.

Will this help avoid vignetting on a mobile setup?

SmallRig states that the filter is designed to help reduce vignetting, which is important on mobile rigs where add-on filters can easily darken the corners of the frame. That does not mean every lens and cage combination behaves the same, but the filter will work cleanly with supported SmallRig systems. The 67mm format and matching accessory ecosystem are part of that. It is a better fit for this kind of setup than adapting a bulkier general-purpose filter.

How is it attached, and is it easy to swap during a shoot?

The filter uses a magnetic attachment system when paired with compatible SmallRig mobile cages and adapter rings. That makes fitting and swapping much quicker than threading a filter on and off each time, which is useful when you are moving between changing light levels. SmallRig also mentions a rotating stop design to keep adjustments controlled and help prevent the filter from shifting out of place. For mobile video work, faster handling is a key practical benefit.
