The 49mm Ice CaNDi-5 ND 1.5 & Polarizer Filter 49mm 5-Stopcombines a solid neutral density effect with a circular polarizer effect. When in use, this filter's 32x filter factor provides a 5-stop exposure reduction. Its 1.5 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create shallow depth of field, which can help isolate your subject.

Simultaneously, this filter can help to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizer filters this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave retarder in addition to the linear polarizing filter. The addition of this quarter wave retarder re-randomizes the polarized light, so it will work with auto focus and exposure functions, which can function poorly when a linear and not a cirular polariaer is used.

This filter is constructed from optical glass for clarity as well as color fidelity and features an aluminum alloy filter ring that can be rotated in order to adjust the intensity of the polarization effect.

Related Questions and Answers

Q: 1. How does the filter attach to the lens?

A: There is an 82mm screw at the bottom.

Q: 2. Does this product have filter threads on front for attaching something like a mattebox?

A: The H&Y Filters RevoRing Variable ND3-ND1000 & Circular Polarizer Filter (67-82mm) does not have front filter threads.

Q: 3. I have 2 questions. 1: Does this filter have a front thread to attach another filter, like a mist filter? 2: Can I stack other revorings? Lets say I want to use the 82-95 VND on a 77mm lens, can I use one of their step up/down rings with this 82-95mm VND here?

A: The H&Y Filters RevoRing Variable ND3-ND1000 & Circular Polarizer Filter (82-95mm) does not have front threads. So with that specific filter you can not stack.

Q: 4. Does it come with a protective cap that works with it?

A: Unfortunately it does not include a protective cap.

Q: 5. Can you attach this to a lens with a UV filter?

A: The H&Y Filters RevoRing Variable ND3-ND1000 & Circular Polarizer Filter (58-77mm) is designed to go onto a lens with out a filter on the lens.

Q: 6. Will this fit a Sony FE4/24-105 G OSS lens with 77mm diameter? Or do you recommend 67-82 VND filter?

A: For the Sony FE 24-105mm f/4 G OSS Lens you can go with either the 58-77mm or the 67-82mm size. The H&Y Filters RevoRing Variable ND3-ND1000 & Circular Polarizer Filter (67-82mm) would definitely work for that lens. I would choose the size based on what other lenses one may want to use this on.

Q: 7. Is this filter showing some kind of pattern when going to higher ND stops?

A: No this does not. It has stops to make sure one does not go beyond the usable range of the filter.

Q: 8. Does this come with a lens cap?

A: Unfortunately, a cap is not included with this filter.

Q: 9. The Circular Polarizer seems to be a permanent part (not removable)? Can it be set to zero strength? thanks,.

A: Both optical elements/foils of the circular polarizer are permanently attached, and this is typical with filters that have two elements. The minimum filter factor available when this is installed on your lens is ND3 (1.5-stop).

Q: 10. Will this fit a Canon RF 24-105? Do i need to take the UV filter too attach it?

A: We suggest the following unit as the canon 24-70mm has a 77mm thread. H&Y Filters RevoRing Variable ND3-ND1000 & Circular Polarizer Filter (58-77mm) BH #HYVNDCP5877 • MFR #RNC77 https://bhpho.to/3j3rfZo
