The Heliopan 86mm #15 Dark Yellow Filteris a basic contrast filter, primarily for use with black and white film, that very strongly darkens skies and blues, increases contrast, and is often used for outdoor photography to emphasize contrast and shadows. There is an approximate 4x filter factor with this filter, requiring an increase of 2 stops for normal exposure.

The front and rear surfaces of the filter both feature a single anti-reflection coating. Each coating helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, they offer protection to the filter substrate while helping to keep the glass clean for longer than uncoated glass.

This Heliopan filter is constructed from Schott glass for increased optical clarity and color fidelity. It features a brass filter ring for durability as well as jamming prevention.

Q: 4. Regarding the Heliopan 52mm Slim Circular Polarizer SH-PMC Filter (705240), does anyone know if this filter will work with the larger Canon lenses (300mm f2.8, 400mm DO ...) that have rear mount drop-in filter holders. The issue is that 52mm screw in filters fit in the filter holder but when sliding the filter holder into the slot in the lens it does not fit because the filter is too thick. Is this particular filter slim enough to work with the above lenses? Please help.

A: Unfortunately this type of filter is built to be used on the outside of the lens, and is too thick to work inside a drop-in filter slot. Most circular polarizers, with their moving parts, will be too thick to use.
