This 86mm Tiffen 86mm ND Filter 3.3-Stopis a solid ND filter with a filter factor of 10x that provides a 3.3-stop exposure reduction. Its 1.0 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

Q: 1. Would a 25-30 second exposure of a waterfall be possible on a partly sunny day at f/22?

A: The best I could tell you is to try it and see. It all depends on what partly sunny is. I have used the 1.2 with a 15 second exposure at F16 and got a great result. But that was a cloudy day. Remember that you can always adjust your ISO to 100 to help some.

Q: 2. Can i screw another filter over this one for more light stoppage?

A: Yes you can put another one over this one and increasethe effect.

Q: 3. Is this filter multi coated?

A: This filter is not multi coated.

Q: 4. Does this filter produce a color cast?

A: This is a 2 stop ND filter. The lighter densities typically do not result in any Infra Red (IR) pollution (color shift). This is typically found when using darker density ND filters without any IR protection. These filters are used for long exposures during which both visible and IR light hit your cameras sensor. The IR light causes the color shift (not the filter). If you plan on shooting any ND filters with darker densities we recommend the Tiffen IRND or NATural ND filters, both have IR protection built in.

Q: 5. Does this filter have coatings to reduce flare and internal reflections?

A: No, this is not a coated filter.

Q: 6. What's the exact weight of this filter in grams? Not the package weight, but the weight of just the filter.

A: The Tiffen 37mm ND 0.9 Filter, weighs in at 40 grams.

Q: 7. Hi!Can the 0.9 and 0.6 Tiffen ND filters be stacked with the B+W ND filters and circular polarizer filters?Additionally, since this Tiffen filter does not have any form of coating on it, what are the effects of that?Thank you!

A: As long as the B+W filters in question have 52mm filter threads on the front of the filter, you would ba able to attach the Tiffen 52mm 0.6 Neutral Density Filter and the Tiffen 52mm 0.9 Neutral Density Filter to the front of the filter. The main issue that may arise from the filter not having coatings would be the chance of obtaining more internal flare or glare from using the filter. However, as such, I would recommend using your lens hood to reduce the occurrence of glare or flare.

Q: 8. Other than having a vignette problem can I stack three of these 3-stop ND filters to achieve 9 stops down? The Big Stopper system is $200, I don't want to pay that, which gives 10 stop reduction. Or do you carry a ND 10 stop filter for $50 or so? Thanks

A: That is correct. While it would certainly create some vignetting, stacking 3 of the 0.9 filters will give you 9 stops of light reduction. If you wanted to use just one filter, you might consider a variable ND:http://bhpho.to/1cCfMcVThis will allow you to adjust the ND effect, while maintaining a relatively slim profile.
