Heliopan High Transmission (HT) Polarizing Filter 8078 | Circular | PMC Coated
This premium polarizing filter enhances color saturation and boosts contrast, resulting in vibrant colors.
- High-end circular polarizing filter with remarkable transmission properties
- Thanks to special polarizing filters, the light loss is only 1.66 stops
- Improved light transmission allows for shorter exposure times
- Increases color saturation and contrast, resulting in vibrant colors
- Also used to suppress reflections on non-metallic surfaces
- Optical glass with a plane-parallel cut for uniform light refraction
- PMC multi-coating reduces reflections to 0.2% per air/glass transition
- Almost no light loss caused by reflection. High scratch resistance
- Coating creates a lotus effect that allows water to simply bead off
- Precisely crafted brass mount. Matte black. Approximately 6.5 mm high
- With front thread for a lens hood or lens cap
- With scale for use with a rangefinder camera
- Manufactured in Germany
Why a Polarizing Filter?
Natural light travels in a straight line in wave form in all directions. Pure sunlight is polarized and has high color purity. When passing through the atmosphere, some of it is scattered, which overlays all colors with a blue-gray haze. This portion can often be reduced or prevented with polarizing filters. Additionally, when light falls at a shallow angle of about 35 degrees on a reflective surface, such as water, glass, plastics, paints (except metallic surfaces), the light is reflected and polarized. When a correctly oriented polarizing filter is used, the reflections are absorbed, allowing the pure colors to reach the film or image sensor. Water surfaces become transparent, the blue tint from sky polarization is dampened, and the colors become much stronger and richer.
The Heliopan polarizing filters come with a rotatable mount with a numbered ring, allowing the desired position and effect to be easily set for any camera type.
What is the Difference Between HT Polarizing Filters and Normal Polarizing Filters?
- The filter factors of polarizing filters usually range between 4 and 8, which corresponds to up to three f-stops. The Heliopan High Transmission (HT) Polarizing Filter has a filter factor of 2 to 3, which corresponds to 1 to 1.5 f-stops.
The Heliopan High Transmission Polarizing Filter has a filter factor of 2 to 3, resulting in only about 1 to 1.5 f-stops of light loss
- HT polarizing filters are ideal for available light and handheld photography, as the reduced light loss allows you to use the shorter shutter speeds of your camera.
- Another advantage is the brighter viewfinder image.
- With this filter, you can use the lower ISO settings of your cameras to achieve the best possible quality.
High-Quality Brass Mount with Front Thread for Attaching Another Filter
The filter has a high-quality brass mount. The mount is extremely stable and very precise. Additionally, brass offers better sliding properties than, for example, aluminum. Thanks to all these properties, the filter can be screwed on and off very smoothly. The mount is matte black to avoid reflections. It also has a front thread for attaching another filter, a lens hood, or a lens cap with a snap mechanism.

Heliopan PMC Multicoating
Reflection on glass/air surfaces is one of the main causes of contrast loss in lenses, which can make demanding photography impossible in extreme cases. Therefore, lens manufacturers put enormous effort into coating their lenses. This quality chain should not be broken by using a filter with inferior coating. The broadband anti-reflection coating, consisting of eight layers on each side, not only reduces reflection in the visible light range to almost zero percent, but it is also water and dirt repellent. This makes it significantly more robust against damage and easier to clean than previous MC filters or a front lens.
