This 67mm 5-in-1 Attachable Filter Kit from SmallRig is ideal for those who need a versatile set of filters that can be adjusted quickly and easily. Simply attach the included magnetic adapter ring to the front of your lens and the filters can then be swapped quickly and easily. A variable ND filter offers 5-stops of exposure reduction for shooting in bright environments or with slow shutter speeds, and a circular polarizer filter helps to reduce glare and reflections. A 1/4-strength Black Mist filter is also included and offers a soft, dream-like diffusion effect. The multicoated German optical glass and CNC-machined aluminum construction make these filters durable and reliable.
