This 67mm Tiffen Water White Glass NATural IRND Filter is a neutral density filter with a 2x filter factor that provides a 1-stop exposure reduction. Its 0.3 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you are able to control depth of field and convey movement more easily. Neutral density filters are intended to not affect the coloration of the image and are ideal for pairing with other filters.

The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible light and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times.

This filter is noncoated, is constructed from Water White glass for increased clarity, and features an aluminum-alloy filter ring for durability while remaining lightweight. It is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch.

Related Questions and Answers

Q: 1. Will this work on a zoom lens at minimum magnification? Or would I need a lens with fixed mm?

A: Will work with pretty much any lens but normal lens are considered to be lens with a focal length between 35mm to 50mm.

Q: 2. is this filter necessary for nighttime videography? And is it worth buying this filter for video or you can do all of the color adjustments in post where you could remove the light pollution and grade to a natural night color?

A: If are shooting on locations at night with light pollution it is best to use a filter like the NiSi 67mm Natural Night Filter. editing in post will not be as good.

Q: 3. Two questions: (1) how thick is this filter, neglecting the thickness of the threads; and (2) why is the "filter factor" 0.6 to 1.5 stop instead of a constant value?

A: The frame is 6.2mm. But once threaded into the lens it is about 3.8mm. And the light loss is just under a stop.. It is not a range.

Q: 4. I am wondering- if you had two of these filters stacked, would you be able to safely shoot the coming eclipse?? Stop wise it would seem so. I already own one and love this filter.

A: Everything that I have read on Canon's website and the Eclipse 2017 website says NO! Regular ND filters will not work. The filter needs to be photographic filters for solar photography. The danger is damaging the camera sensor, your eyes, and the camera electronics. You want to get a White Light Solar Filter, such as made by StarGuy.

Q: 5. Does this fit on a Sigma 17-50mm f/2.8 EX DC OS HSM Zoom?

A: Yes, the Sigma 17-50 you've described is a 77mm diameter lense. This filter will fit.

Q: 6. How does this compare to the wide angle low profile filter that is about $40 cheaper? Which one is recommended for videography/filmmaking?

A: The wide angle version is meant for wide angle lenses to prevent vignetting. Otherwise, both versions have the same purpose in mind.

Q: 7. Does this filter have a hard stop at both ends or does it continuously turn?

A: Continuously turn

Q: 8. Will the filter fit into the leather pouch with the 7282 step up ring attached to it? It is hard to tell from the photos.

A: Yes the filter fits in the leather pouch with the 7282 step up ring attached or detached to it. I think you can even fit both step up rings into the leather pouch along with the filter. You could use a small microfiber cloth to separate them from the filter.

Q: 9. Recommended circular polarizing filter for Canon 100-500 to ne used in snow conditions also use clear filter on lens allways?

A: Tiffen 77mm Digital HT (High Transmission) Circular Polarizing Multi-Coated Filter have front threads of 77mm if you preffer to have an uv filter in the front. However this filter has the highest scratch-resistant coatings. If you would be shooting outdoors the filter factor cuts between 1.2-1.5 stop of light to help correct exposure when shooting with snow.

Q: 10. What size Push-On lens cap do I need for this filter? The frame of the filter seems to be larger than 82mm

A: If you are planning on keeping the step ring on while you shooting yes you will have to buy an 82mm cap
