The Tiffen 6.6 x 6.6" ND 2.1 Filter is a solid neutral density filter that reduces exposure by 7 stops. With a density of 2.1, it darkens the entire image, enabling you to use a wider aperture or slower shutter speed than usual. This adjustment lets you control depth of field and capture movement more effectively. Importantly, neutral density filters don't impact color, making them great for use alongside other filters.

Crafted using ColorCore technology, this filter involves laminating the substrate between two optical glass pieces and grinding to an exceptional tolerance of 1/10,000th of an inch. Its dimensions are 6.6 x 6.6" / 167.6 x 167.6mm.
