Moment started out as a smartphone and drone accessories brand but they're growing. The company has announced three sets of variable ND filters for DSLR and mirrorless cameras. The screw-in filters come in a 67mm, a 77mm, and an 82mm as a 2-5 stop or 6-9 stop.
Variable ND filters attached to the front of the lens and control the amount of light that enters the camera. It's different from a fixed ND filter as a variable ND filter allows you to adjust the amount of light. It works by using two layers of polarizing glass that are placed opposite of each other. The inner layer is fixed to the lens and the outer layer is attached to a mechanical ring that can be rotated to reduce or increase the amount of light. Both fixed and variable ND filters are ideal for outdoor shooting or if you want to make brighter scenes darker. They also provide more control over depth of field and shutter speed.
What makes the Moment variable ND filter unique is the ND number is etched so you can see it from behind the viewfinder. The filters also feature a hard stop on both ends, a knurled grip for control and you can still use them with your camera lens cap. The 2-5 stop (ND4 - ND32) is ideal for general use and the 6-9 stop (ND64 - ND512) is for brighter conditions and log shooting above ISO 400.
The competition among variable ND filters is thick and not all are built the same. Some can vignette, others cast unwanted colors or cross polarize. The PolarPro Peter McKinnon Edition variable ND filters come to mind. They too are available in 67mm, 77mm, and 82mm as 2-5 stop or 6-9 stop for $249. Tiffen is another option that's a bit more versatile. Instead of 3 stops of control on one filter, its variable ND filter provides 2 to 8 stops for $107, $117 and $118 respectively. Moment finds itself in the middle delivering similar quality at a lower price than the McKinnon line while both offer less than the Tiffen filters.
Moment also released two variable ND filters for the DJI Mavic 2 in a 2-5 stop or 6-9 stop. The filters are red and feature the same knurled grip and hard stop on both ends. Previously, Moment released an anamorphic lens for the DJI drones as well as some handy smartphone filters to go along with Pro Camera app.
