The Haida 77mm NanoPro MC UV/IR Cut Filter is an ultraviolet and infrared control filter that is useful for digital cinematography as well as still photography. While recording video with a CCD or CMOS camera, multi-stop neutral density filters are used to maintain proper exposure by compensating for increased light levels when widening the camera lens's iris to obtain a narrower depth of field. As the increased amount of light passes through multi-stop neutral density filtration, visible light is progressively blocked, while infrared light is allowed to pass through. As the proportion of infrared light that reaches the sensor of a camera being used for digital cinematography becomes greater, the results can show unwanted color shifts, particularly in dark areas of the frame such as shadows, where the appearance of black is dominant.

When the Haida 77mm NanoPro MC UV/IR Cut Filter is applied, ultraviolet light waves are blocked at 390 nanometers along with infrared light waves at 750 nanometers, helping to ensure that light falling on a digital camera sensor is limited to the visible spectrum. When used along with multi-stop neutral density filters while recording with a digital sensor, potential infrared color shifts are prevented or minimized, preserving color accuracy throughout the frame. This filter may also be used to help ensure that the appearance of unwanted blue casts is reduced while recording digital video or still photos under daylight that also features intense ultraviolet light.

The front and rear surfaces of a Haida 77mm NanoPro MC UV/IR Cut Filter each include eight layers of interference coatings, which allow it to limit the light that falls on a digital camera sensor to the visible spectrum. When combined with a wide-angle lens, lower-frequency wavelengths of visible light associated with yellow, orange, and red colors passing through the filter and along that lens type's curved edges can be impeded in a significantly greater degree than higher-frequency wavelengths of visible light associated with blue and violet colors. This can result in an unwanted green cast within an image taken with a Haida 77mm NanoPro MC UV/IR Cut Filter and a wide-angle lens. To avoid such color shifts using this filter, it is recommended not to be used with lenses that are intended to provide an angle of view greater than 60°.

The Haida 77mm NanoPro MC UV/IR Cut Filter is constructed from optical glass for clarity and color fidelity. To prevent internal ghosting and reflections, each glass surface includes 10 layers of anti-reflection coatings, which also offer greater protection to the filter substrate and help keep it clean for a longer period of time. The Nano coating associated with the Haida 77mm NanoPro MC UV/IR Cut Filter provides an additional layer that results in an improved beading effect when the surface comes in contact with water or oil, allowing for more efficient cleaning.

Related Questions and Answers

Q: 1. Does the filter have a thread on both ends? One end male, the other end female?I need to attach the filter to the lens, then screw an ND filter in front of it. Can that be done?

A: Yes, this filter has threading on the front and back so it can be stacked with other filters and allow for lens caps to properly connect with it.

Q: 2. What is the thickness of the ICE-CUT100 (ICE 100mm UV/IR Cut) filter?

A: The filter is 2mm thick.

Q: 3. will this filter work on a Canon 400mm f5.6 lens? will the filter interfere with the bayonet hood on the lens?

A: If you are referring to this lens, Canon EF 100-400mm f/4.5-5.6L IS II USM Lens, you should be fine using that filter with the hood.

Q: 4. Has anyone used one of these on a Sony A7s series camera? Both versions of the A7s come with a Low Pass filter, which I believe cuts down much of what this filter is intended to do, so is it irrelevant?

A: I haven't used it on a Sony and don't know their specs, but generally Low Pass filters don't cut UV, and don't cut all Infra Red. You can test by taking a photo of the IR cell on a TV remote while pressing one of its buttons, if the photo shows a light in the cell, IR is getting through. I normally use this lens for work where extreme sharpness or clarity is critical or when using tungsten lighting.

Q: 5. is the level detachable? If so, can I still use the lens hood on my rf 24-105mm without the level?

A: The lever is detachable but the filter ring is too large to be used inside the Canon hood. A screw on hood could be used instead such as this: https://bhpho.to/35j7SrF

Q: 6. Hi, does this filter have threads in both sides to allow stacking another filter (or cap) over it? Thanks!

A: Yes, It's 77mm on both sides allowing for additional filters or a 77mm lens cap to be placed on top.

Q: 7. Has anyone tried this on a full spectrum camera? I have a Nikon D7000 that’s converted to full spectrum and I’m looking for a filter to revert it back to visible spectrum when the need arises. Looking to see how the results are before I pull the trigger.

A: Unfortunately, we're not aware of any tests that have been performed with this particular filter on a camera which has been converted for full spectrum use. Your results may vary.

Q: 8. Is this filter useful when used on DSLR with WB on auto to photograph the milkey way?

A: Yes, the Haida 55mm NanoPro MC Clear-Night Filter will help with shots at night. of the Milky way. Best is not to have the camera set to Auto White balance and to have it set to day light.

Q: 9. Can this be used with K&F magnetic rings?

A: The Haida NanoPro Magnetic Clear Night Filter can't be used with K&F magnetic rings.

Q: 10. Does this come in 72mm?

A: Unfortunately no. The NiSi 77mm UV IR-Cut Filter for True Color VND and Swift System is only made in the 77mm or 82mm sizes.
