This NiSi Circular Advance Filter Kit contains three filters that are compatible with lenses that feature 77mm front filter threads. They can be used individually or in various combinations to improve the results of your photography. Included is a general-use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight; a circular polarizer filter that helps to reduce reflections as well as glare by filtering out light that has become polarized due to reflection from a non-metallic surface; and a filter to reduce the appearance of light pollution in images or video that include the night sky and illumination from artificial light sources.
A filter pouch is included to store and transport this filter kit. It features four padded, nonabrasive pockets plus a touch-tab fastened closure.
NiSi 77mm PRO Nano HUC UV Filter
- Absorbs UV light and reduces bluish cast of daylight
- Does not require adjustments to exposure while in use
- Eliminates ghosting and reflections by helping to maximize light transmission
- NiSi HUC Nano coating provides enhanced protection to the filter's substrate and results in an improved beading effect when in contact with water or oil for greater cleaning efficiency
- Creates no additional coloration or contrast
- General protection filter reduces dust, moisture, and scratches from reaching lens elements
- Constructed from optical glass for clarity
- Brass filter ring helps to prevent jamming and provides additional strength
- Side knurling to provide a more textured grip when mounting or removing filter from a lens
- 77mm front filter threads allow for use with other filters
NiSi 77mm PRO Nano HUC Circular Polarizer Filter
- Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface
- Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light
- Clears up haze in distant landscapes and provides more saturated, vivid colors
- Strongest effect when used at a 90° angle from the sun
- Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features
- NiSi HUC Nano coating provides enhanced protection to the filter's substrate and results in an improved beading effect when in contact with water or oil for greater cleaning efficiency
- 2 to 2.5x filter factor reduces exposure by 1 to 1.3 stops
- Constructed from optical glass for clarity
- Brass filter ring helps to prevent jamming and provides additional strength
- Filter ring can be rotated to adjust the intensity of the polarization effect
- Side knurling to provide a more textured grip when mounting or removing filter from a lens
- 77mm front filter threads allow for use with other filters
NiSi 77mm Natural Night Filter
- Reduces the appearance of light pollution in images or video that include the night sky and illumination from artificial light sources
- For cameras with daylight film installed or a digital camera system with its daylight white balance setting selected
- Absorbs the yellow light from sodium-vapor or mercury-vapor lamps, common light sources within urban areas
- Enhances the visibility of astronomical objects, and where they appear, artificial light sources are more clearly defined with less glare and improved contrast
- 1.5 to 2.8x filter factor reduces exposure by 0.6 to 1.5 stops
- Constructed from optical glass for clarity
- Each glass surface includes one layer of nano coating that results in an improved beading effect when in contact with water or oil for greater cleaning efficiency
- Aluminum alloy filter ring for durability while remaining lightweight
- 77mm front filter threads allow for use with other filters
NiSi Filter Pouch for up to Four 95mm or 100 x 100mm Filters
- Designed to accommodate up to four 95mm or 100 x 100mm filters
- Soft, nonabrasive interior lining
- When photographing with a tripod, rear touch-tab loop allows placement around a tripod leg, putting filters in more immediate reach
- Touch-tab-fastened closure
- Durable canvas construction
