This 86mm Tiffen Coarse Combination 85/ND Filter blends both an amber color conversion 85 and a 0.6 neutral density filter. The ND filtration provides a 2-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) film.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

Q: 6. 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: There is no published list of compatible filters for that filter holder--the only filters guaranteed to fit are those provided by Canon. Because the Formatt Hitech 52mm Firecrest ND 1.5 Filter (5-Stop) has a "super-slim" design, it may work.
