The 3-stop, 4 x 5" Tiffen 3-Stop Graduated ND Filter 4x5"is a graduated neutral density filter that helps to specifically darken skies and other bright areas of the image. The filter is densest at the edge and tapers to clear by the middle, with a hard-edged line of transition between the density and clear areas. Neutral density filters do not affect the coloration of the image and the 0.9 optical density provides a 3 stop reduction in light from entering the lens.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 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.

Note: A horizontal orientation filter's line of transition runs parallel to the long side of the filter.

Related Questions and Answers

Q: 1. what is the thickness?

A: The Tiffen 4 x 6" Water White ND filters are 4mm thick.

Q: 2. what kind of lens cap can be used? (It appears too shallow for normal lens caps)

A: You can use a screw in lens cap. There is one listed as an accessory below the item on our web page.

Q: 3. are these stackable?

A: Yes, this filter has a front thread so you can attach another filter.

Q: 4. Does it come with plastic case?

A: Yes.

Q: 5. What size lens cap fits the Tiffen 82 mm variable ND filter? Thank you!

A: The Tiffen 82mm Variable Neutral Density Filter does not have front filter threads, so standard lens caps are incompatible. The Kaiser 100mm Push-On Lens Cap, BH #KALC100, is a little large. Adding gaffer tape around the inside edge does allow the cap to fit.

Q: 6. Would the Formatt Hitech 82mm Firecrest Graduated ND 0.9 Filter which has 7.5 thickness ring produce vignetting when using on a Canon 24-70 2.8L II lens (82mm filter size) at 24mm f/2.8? (I'm concerned due to the 7.5mm thickness).Thank you very much!

A: No, it is not too wide for the filter to create vignetting.

Q: 7. Would this fit the Sigma 18-35mm f/1.8 DC HSM Art Lens for Canon EF?

A: It will work with a step up ring but you can get one that is 72mm to fit directly.

Q: 8. Does the filter have threads on both sides?

A: Yes, the 7artisans Photoelectric 82mm GND0.9 Filter is threaded on both sides.

Q: 9. I have the LEE 100mm foundation kit with the 105mm CPL. Can I use this Hitech filter in front of my CPL - And then thread the CPL filter on to this graduated filter?

A: No, this filter rotates like the polarizer. It'll be too hard to see the effect of the ND moving around and the polarizer moving. I found it hard enough to see the effect of the 2 stop ND thru my lens in dawn light. I had to put a mark on the metal ring to see where the center of the top of the filter is so I could quickly set up the shot.

Q: 10. I wanted to double check that this filter does in fact have front filter threds for stacking other filters because one buyer said it did not have front threads. Can soneone confirm that it does have front threads? Thank you.

A: Yes, this filter has front threads.
