The Tiffen 4 x 5.65" Double Fog 1/8 Filter simulates the effects of natural fog or mist by creating a soft glow around highlights and lowering the overall contrast of the scene. When compared to the standard Fog filter, this filter places greater emphasis on lowering the contrast while maintaining sharpness and minimizing the effects of flare. The 1/8 density provides less fog effect that the 1/4 and requires no exposure compensation.

Tiffen filters are 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 5.65" / 101.6 x 143.5mm.

Provides a fog-like effect with dramatically lowered overall contrast.

Q: 1. Are these IR cut?

A: Yes, the SmallRig Cine Neutral Density Filter (4 x 5.65", 3-Stop) attenuates infrared light from 400nm to 1100nm.

Q: 2. Is this the correct filter to use on a NiSi 150mm Holder System for the Nikon 14-24 f/2.8g lens? If so, would it prevent dust and sand from making contact with the lens?

A: You can fit a 6 x 6 filter into a 150mm filter holder. (The 6 x 6 is only 2mm larger) You would have to put the filter in the rearmost slot. This will protect the lens from direct hits. However, you may wish to do what we do on a movie set and use black paper tape to seal the filter so that no sand/dust/water droplets can get in.

Q: 4. Hi, Does this kit work on alexa camera ? do anyone know what ll it look like after using at alexa ?Tks

A: These filters will work with an Alexa camera as long as you have a Matte Box or Filter Holder capable of holding 4x5.65 filters which are 4mm thick. You may start to see IR pollution when using the higher densities in this kit, so we recommend that you use Full Spectrum ND filters with an IR filter built in such as the ones listed below:IRND1.2a href= http://www.bhphotovideo.com/c/product/572932-REG/Tiffen_45650IRND12_4x5_65_Neutral_Density_1_2.html target= _blank http://www.bhphotovideo.com/c/product/572932-REG/Tiffen_45650IRND12_4x5_65_Neutral_Density_1_2.html/aIRND.9a href= http://www.bhphotovideo.com/c/product/572944-REG/Tiffen_45650IRND9_4x5_65_Neutral_Density_0_9.html target= _blank http://www.bhphotovideo.com/c/product/572944-REG/Tiffen_45650IRND9_4x5_65_Neutral_Density_0_9.html/aIRND.6a href= http://www.bhphotovideo.com/c/product/572942-REG/Tiffen_45650IRND6_4x5_65_Neutral_Density_0_6.html target= _blank http://www.bhphotovideo.com/c/product/572942-REG/Tiffen_45650IRND6_4x5_65_Neutral_Density_0_6.html/aIRND.3a href= http://www.bhphotovideo.com/c/product/572940-REG/Tiffen_45650IRND3_4x5_65_Neutral_Density_0_3.html target= _blank http://www.bhphotovideo.com/c/product/572940-REG/Tiffen_45650IRND3_4x5_65_Neutral_Density_0_3.html/a

Q: 5. Is the filter holder is available along with the Redrock micro Matt box,or should I buy as an accessory, which size filter is compatible with Canon cn-e 14.5 to 60mm t/2.6 lens(133 front diameter)

A: The filter holder in the Redrock micro Matt Box holds up to 4x5.65" filters. But if one is using the Canon cn-e 14.5 to 60mm t/2.6 lens with a 133mm diameter, one will need a Formatt Hitech 165mm Lucroit Filter Holder Kit: https://bhpho.to/2Lazzp8 for 165mm filters.such as the Formatt Hitech 165 x 165mm Firecrest ND 0.3 to 0.9 Filter Kit: https://bhpho.to/2KRpcHF

Q: 7. What is the size of this filter?

A: Series 9 filters by Tiffen are a unique filter system once popular with older lens and camera design. Requiring a Series 9 adapter ring, this system allows you to use one standard size filter (Series 9) on many lens sizes. Series 9 filters, although screw-on style, require a bit more work to set up. The glass filter drops into the adapter ring and is held securely in place with the included retaining ring (adapter ring sold separately). Series 9 filters have no threads. Although these filters are no longer as popular as they used to be, they allow the use of filters for harder to fit lenses, a common problem with older camera lenses.

Q: 8. What is the differences between this model and http://www.bhphotovideo.com/c/product/398871-REG/Schneider_68013038_138_mm_True_Linear_Polarizing.htmlIt seems like its just different descriptions but the same product. The only noticeable difference is a 10 year warranty on the more expensive model. What exactly does this cover? Does it cover it breaking?

A: Basically, there are two types of Polarizing filters; Linear and Circular. Linear are used for manual focusing as they can confuse AF sensors. Circular filters are designed for AF lenses and cameras but can be used on manual focus cameras as well. For more details on the two, please see: http://bhpho.to/MF21zoThe Schneider 138mm True-Linear Polarizing Glass filter is optimized for motion picture and television cameras. Having an extinction ratio of ER 374, the Schneider True-Pol is 12-times more effective than other polarizing filters. The 138mm Circular Ultra Polarizing Filter from Tiffen is a similar filter yielding a more intense look to your images and is designed for AF cameras. Because of manufacturing differences, circular polarizing filters cost more than comparable linear filters. Both filters come with ten year warranties that cover manufacturing or workmanship defects.

Q: 9. Will this work in the Kase k9 100x100mm filter holder ?

A: The K&F Concept 100 x 100mm ND8 Filter (3-Stop) is compatible with the Kase K9 Filter Holder.

Q: 10. Dear Sir,does this filter kit correct the IR pollution just like Tiffen's another ND filter with IRND marked in day time?Thanks and regards,Simon

A: Tiffen ND filters will not correct IR pollution unless IR is indicated in the name of the filter such as the 4 x 5.65 Full Spectrum IRND 1.2 filter http://bhpho.to/1oua78J, since IR is on a different wavelength than the visible spectrum.
