This NiSi M75 75mm Professional Kit includes six filters that can be used individually or in various combinations to improve the results of your photography. Included are two neutral density filters that can be used to create a darkening of the entire image; a medium-edge graduated neutral density filter, which prevents overexposure in specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image; a hard-edge reverse-graduated neutral density filter that can be applied to darken bright skies, specifically during a sunrise or sunset, while also allowing for a normal, unaffected exposure in the other regions of the image; a filter to reduce the appearance of light pollution in images or video that include the night sky and illumination from artificial light sources; plus a circular polarizer to prevent distracting reflections or glare.
To allow these filters to be placed in front of a lens, this kit contains an M75 Filter Holder that is designed to allow for the convenient use of up to two 75mm wide, 2mm thick filters along with the included circular polarizer.
A microfiber cleaning cloth and a filter brush are provided for cleaning and maintenance of the filters, as well as padded pouch for storage and transport.
NiSi M75 Filter Holder Kit
- Durable aluminum alloy filter holder provides two pairs of filter slots, a configuration that accommodates up to two separately available 75mm wide, 2mm thick filters
- Each slot is designed to grip an installed filter only along the surface of the filter’s edges, avoiding contact with the filter’s front or rear-facing surfaces
- Use of the filter holder can be easily accomplished by first screwing the included 67mm adapter ring onto a lens with 67mm front filter threads
- Separately available step-up rings allow the adapter ring to be used with lenses that have 40.5mm, 43mm, 46mm, 49mm, 52mm, 55mm, 58mm, and 62mm front filter threads
- Pull-and-release locking pin on filter holder allows for a reliable connection to the 67mm adapter ring, which allows the holder to be rotated 360 ?
- Screw-in locking pin can be used to prevent any rotation of the filter holder, further securing the position of an installed filter
- 67mm adapter ring accommodates included NiSi M75 Circular Polarizer Filter and allows it to rotate for adjustment of its effect
- When combined, filter holder and 67mm adapter ring allow for easy installation or removal of the circular polarizer
- Padded pouch included for storage and transport
- When photographing with a tripod, rear loop allows placement of the pouch around one of the tripod’s legs, putting filters in more immediate reach
NiSi 75 x 80mm Nano IRND 1.8 Filter (6-Stop)
- Neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required
- Providing a 6-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily
- Filter does not affect coloration of the image and is ideal for use with other filters
- Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths to maintain color neutrality and suppress color casts due to increased exposure times
- Constructed from optical glass for clarity
NiSi 75 x 80mm Nano IRND 3.0 Filter (10-Stop)
- Neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required
- Providing a 10-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily
- Filter does not affect coloration of the image and is ideal for use with other filters
- Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths to maintain color neutrality and suppress color casts due to increased exposure times
- Constructed from optical glass for clarity
NiSi 75 x 100mm Nano Medium-Edge Graduated IRND 0.9 Filter (3-Stop)
- Graduated neutral density filter darkens bright areas of an image, such as skies, while leaving the remainder of the frame unaffected
- 8x filter factor provides up to a 3-stop reduction of light in selective areas
- Medium-edged line of transition between the dense and clear areas
- Useful for images that include elements like rooftops and mountains that protrude into the sky
- Filter does not affect coloration of the image and is ideal for use with other filters
- Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths to maintain color neutrality and suppress color casts due to increased exposure times
- Nano coating provides an improved beading effect with water or oil for more efficient cleaning
- Constructed from optical glass for clarity
NiSi 75 x 100mm Nano Hard-Edge Reverse-Graduated IRND 0.9 to 0.15 Filter (3 to 0.5-Stop)
- Effectively darkens bright skies, specifically during a sunrise or sunset, while allowing for a normal, unaffected exposure in the other regions of the image
- 3-stop band of density that tapers to a 0.5-stop density at the edge above it while directly above a clear area creates a neutral density pattern that matches the positioning of the sun when it is at, or immediately above, the horizon
- Density pattern corresponds to the brightness pattern of the sun when it appears at or is closer to the horizon as opposed to a higher angle, which creates an increase in brightness that is more prominent on both sides of the sun than above it
- Hard-edged line of transition between the 3-stop band of density and the clear area below it is useful for hard transitions between the sky and land
- 3-stop to 0.5-stop gradation is applicable to multiple regions of brightness within the sky
- Filter does not affect the overall coloration of the image
- Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths to maintain color neutrality and suppress color casts due to increased exposure times
- Nano coating provides an improved beading effect with water or oil for more efficient cleaning
- Constructed from optical glass for clarity
NiSi 75 x 80mm 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
