This 2-stop, 46mm Tiffen Graduated ND Filter 46mm 2-Stopfrom Tiffen Graduated ND Filter 46mm 2-Stopis densest at one edge where it corresponds to a reduction of light entering a lens by 2 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 0.6 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 0.6 density corresponds to a 4x filter factor and 2-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
• 46mm front filter threads allow for use with other filters

Q: 1. 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: 2. Can this variable B+W ND be stacked with a B+W ND 10-Stop filter in order to achieve a 13-15 Stop result?

A: Yes, but shooting thru several pieces of glass will reduce image quality.

Q: 3. What are the filter and stop factors for this filter?

A: The filter factor is 3 and the stop loss is 1 and 2/3 stop

Q: 4. What’s the transmission value of this filter? Thanks

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

Q: 5. 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: 6. Does this fit on a Canon RF 24-105mm L lens? Without touching the glass?

A: Yes it fits on any lens that has a 77mm filter thread such as the Canon RF 24-105mm f4 L lens.

Q: 7. 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: 8. 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: 9. 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: 10. 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.
