This 4 x 5" Tiffen 81EF/ND Filter 4x5" 2-Stopblends both an amber light-balancing 81EF and a 0.6 neutral density filter. The ND filtration provides a 2-stop exposure reduction for darkening the entire image in order to photograph with a wider aperture or slower shutter speed than normally required. The 81EF filtration covers the entire filter plane and lessens the color temperature by 650K, enabling the ability to attain 3200K balance when the prevailing light source is 3850K.

This filter 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. This filter measures 4 x 5" / 101.6 x 127mm.

0.6 ND filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

81EF light-balancing filter decreases color temperature and provides a warming effect.

Related Questions and Answers

Q: 1. Will this ND Filter work well with the Tokina 11-16mm f/2.8 II Lens? I am unsure if I will get the notorious X-Pattern when blocking the light at 8-Stops, because as mentioned it is a very wide lens (11-16mm). Does anyone have experience? I would buy the lens and the filter together, it seems a good bundle for land- and seascape.

A: Thin version, not for the x pattern, but because the thick version comes into view on wide angle lenses 24mm.

Q: 2. Should this filter have a physical hard stop at both ends? I have a different brand variable ND filter on my 50mm, and the adjustment ring will stop at both ends of the spectrum, where this one just keeps spinning with not stop. Is that a defect or how it's made? I find it annoying to not have the tactile 'stop', so to speak, of open or closed filter.Thanks for your help!

A: Adam,I have one and it does not have a stop, which is annoying. On the outside ring of the filter are Min - Max calibrations, which are not of much help. I just eyeball it until I have the scene, or photo exposed how I want it. This lack of a hard stop also caused me to unscrew the filter from my lens when I was just starting out with it. The last inconvenience is the lack of a lens cap to go over it which is a hassle when you are running and gunning. That said, the filter is a big help for quick lighting adjustments... once you get used to it.

Q: 3. What is the material of the ring? Aluminum? Brass?

A: Aluminum

Will it fit onto my Canon EF-S 18-55mm f/3.5-5.6 IS STM Lens? If not what mm size Tiffen Variable ND Filter should I purpose? Thank you

A: This filter will fit any lens with a 58mm filter thread. Look at your lens, usually near the end of the lens the filter size is marked next to a O with a slash through it. This indicates diameter. Otherwise, you can look up the specs of your lens filter diameter on your manufacturers website, or through the B&H website.

Q: 9. Will this 9mm thick ND filter work on Nikon 10-24mm Wide angle or is there a thin version?Thanks in advance, Terry

A: The Tiffen 77mm Variable Netural Density Filter may cause vignette on a Nikon 10-24mm lens. B+W makes a thinner profile variable ND filter with a larger filter ring that will be better for use with a wide angle lens: http://bhpho.to/OH7mr4
