The 5 x 6" Tiffen Combination 85/ND Filter blends both an amber color conversion 85 and a 1.2 neutral density filter. The ND filtration provides a 4-stop exposure reduction for darkening the entire image in order to photograph with a wider aperture or slower shutter speed than normally required. The 85 filtration covers the entire filter plane and converts the color temperature to 3400K for use with type A (tungsten) films.

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 5 x 6" / 127 x 152.4mm.

Q: 2. Will this filter be SLIM ENOUGH to slot into a Canon 300/2.8 and 400/2.8 lens? I have the drop-in filter holder that accommodates 52mm screw-in filters, but they need to be SLIM enough to fit into the drop-in slot on top of the 300 and 400 mm lenses. Will it work?

A: The Ultra Firecrest series filters exhibit greater clarity and have lower reflectivity than the original Firecrest filters.

This additional step helps to ensure flatness and consistency for improved image quality.
