This 4-stop, Series 6 Heliopan ND Filter is an ND filter with a 16x filter factor that provides a 4-stop exposure reduction. Its 1.2 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create shallow depth of field, which can help isolate your subject.

Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters. This Heliopan filter is constructed from Schott glass for increased optical clarity and color fidelity. It features an aluminum-alloy filter ring for durability while remaining lightweight.
