This 4-stop, 82mm Tiffen Graduated ND Filter 82mm 4-Stopfrom Tiffen Graduated ND Filter 82mm 4-Stopis densest at one edge where it corresponds to a reduction of light entering a lens by 4 stops and tapers to clear at the other edge. Its gradation can be used to selectively darken an image from edge to edge, allowing for wider apertures or reduced shutter speeds. While this graduated attenuator/blender's 1.2 density can be applied to bright skies, the remaining regions of the image are exposed with a progressively decreasing effect.

This filter is constructed using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, then mounting to precision metal rings.

• Darkens bright areas of an image, such as skies, while the remaining regions of the image are exposed with a progressively decreasing effect
• Maximum 1.2 density corresponds to a 16x filter factor and 4-stop exposure reduction
• Constructed from optical glass for clarity
• Noncoated
• Aluminum-alloy filter ring assembly for durability while remaining lightweight
• Rotatable filter ring assembly allows for gradation positioning along the horizon line
• 82mm front filter threads allow for use with other filters

Related Questions and Answers

Q: 1. What is the Low Profile Titanium Lock Ring? Is this a way of locking the filter, to stop it rotating?

A: The lock ring holds the glass in the main filter ring. It is low profile to avoid vignetting. This has nothing to do with the rotation of the filter for polarization.

Q: 2. I do not see a high transmission ultra-slim or low profile version of this filter. Will this polarizing filter cause vignetting with wide angle lenses?

A: when using wide angle lens we highly suggest using filter with slim profiles to avoid vignetting.

Q: 3. I have this filter in the 55mm size but the lens caps that I have will not stay on for more than a few seconds, the slightest pressure on them pops the cap off the lens. Anybody find a lens cap brand/model that works with this filter?

A: The Sensei 55mm Center Pinch Snap-On Lens Cap is compatible with the Tiffen 55mm Digital HT (High Transmission) Circular Polarizing Multi-Coated Filter.

Q: 4. 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: 5. I'm looking for a 62mm polarizing filter for a 18-250 zoom I recently bought at B & H, on top of wanting a decent one I want one with a solid lens cap, I will be leaving this on the lens allot and a good filter is not much use if it is dirty or scratched. I previously bought B+W that had a useless plastic cap that would not stay on. Will the sigma lens cap attach to this or does it come with a decent one?

A: The Tiffen 62mm Digital HT (High Transmission) Circular Polarizing Multi-Coated Filter is front threaded at 62mm's so you will be able to use the Sigma lens cap as designed.

Q: 6. Does this come with a protective case for the filter?

A: Yes, the B+W MRC Nano Master #803 ND0.9 Filter (82mm) comes with a drawstring filter pouch for protection.

Q: 7. Will this filter produce an image with yellow sun or white color cast sun?

A: The Hoya ProND-100000 Neutral Density 5.0 Solar Filter (82mm, 16.6-Stop) will produce a yellow/color cast not white of the Sun. One of the safest filters does produce white color. And that is, https://bhpho.to/3Q9J3n6.

Q: 8. Will this filter work with both a 58mm tele lens and 18mm wide lens?

A: This filters can work with any lens that has a 67mm front thread. However, you may experience vignetting on wider lenses.

Q: 9. What’s the transmission value of this filter? Thanks

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

Q: 10. Can this filter be stacked with other 67mm ND filters?

A: Yes, it is possible to stack this B+W MRC Nano Master #802 ND 0.6 Filter with other 67mm filters. However, it's important to note that the risk of vignetting would be higher when stacking more than one filter at a time and if the lens has a wide angle focal length.
