This 67mm Tiffen Water White Glass NATural IRND Filter is a neutral density filter with a 128x filter factor that provides a 7-stop exposure reduction. Its 2.1 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. Is this filter recommended for digital cameras as well, like the Lumix FZ200?

A: Yes, the Tiffen 52mm Digital HT (High Transmission) Circular Polarizing Multi-Coated Filter is compatible with the Panasonic Lumix DMC-FZ200 Digital Camera and would fit onto the 52mm filter threads on the front of the lens, and would be recommended for usage to reduce or eliminate glare and reflections from non-metallic items and (depending on your position and the position of the sun) can also darken/deepen the blue in the sky on blue sunny days. By removing glare, it would also slightly increase teh color saturation and contrast of your image.

Q: 2. What’s the transmission value of this filter? Thanks

A: Filter Factor 2.3x (1.2-Stop) to 2.8x (1.5-Stop)

Q: 3. I've read and heard online that this filter effectively cuts some measure of IR. How true is this?

A: Syrp does not list any specifications on IR transmittance. Without a listed specification, this is subject to product variance. It is impossible to guarantee a specific IR attenuation.

Q: 4. 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: 5. 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: 6. Is it affective?

A: Yes, this filter works very well to reduce light pollution and produce cleaner sharper images.

Q: 7. 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: 8. Looking for a 77mm lens filters for my new nikon 70-200 f2.8. I'll be using in Iceland in winter when it might be gray overcast with lots of white snow? any suggestsion? on d750 camera

A: We recommend this circular polarizing filter, which will help you to eliminate any reflected light when shooting around water. It will also make blue skies pop and white clouds pop if you happen to encounter those conditions. We also recommend a protection filter such as a href= https://www.bhphotovideo.com/c/product/533244-REG/Tiffen_77HTDUC_77mm_Digital_HT_High.html target= _blank https://www.bhphotovideo.com/c/product/533244-REG/Tiffen_77HTDUC_77mm_Digital_HT_High.html/a

Q: 9. Does this filter have a hard stop at both ends or does it continuously turn?

A: Continuously turn

Q: 10. Is the front of this threaded to stack a diffusion filter with?

A: The front threading is mainly for use with a standard pinch type lens cap but it can also accept another filter.
