This 4 x 4" Tiffen ND Filter is a solid neutral density filter providing a 3-stop exposure reduction. This 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 4" / 101.6 x 101.6mm.

Q: 8. What size lens cap fits the Tiffen 82 mm variable ND filter? Thank you!

A: The Tiffen 82mm Variable Neutral Density Filter does not have front filter threads, so standard lens caps are incompatible. The Kaiser 100mm Push-On Lens Cap, BH #KALC100, is a little large. Adding gaffer tape around the inside edge does allow the cap to fit.

Q: 10. Is this filter reflect or does it absorb the light? I am worried about heating of the surface of the filter.

A: This is a Neutral Density filter which is designed to limit the amount of light reaching your cameras sensor. It works very similarly to a pair of sunglasses. This particular ND filter is 5 stops (1.5) meaning only 1/32 of all light passes through it. This filter is commonly used in sunlight without any issues regarding the surface of the filter heating.
