The Hoya 67mm Digital Filter Kit II for Photographyincludes a UV (C) HMC filter, a circular polarizer filter, and a 3-stop neutral density filter in a convenient filter pouch. This kit provides everything necessary to get started with filtration for your digital camera.

The UV (C) filter is a multi-coated filter with a slim mounting ring. This makes it useful for wide-angle lenses to avoid potential vignetting. Also, the UV filter itself is a general use, clear filter that helps to absorb ultraviolet light. No additional coloration or contrast is provided, allowing you to pair this filter with others. It is also useful as a general protective filter to leave on lenses at all times. Filters help to reduce dust and moisture from reaching your lens element and provide additional protection in case of drops or situations where scratching could occur.

Hoya HMC filters are multi-coated for reducing flare, ghosting, and reflections on the filter surface. As a result, over 97% light transmission is possible, providing you with additional contrast and high color fidelity.

A circular polarizer filter helps 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 polarizing filter arranges, and 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 plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

A neutral density filter has several uses and offers the possibility to achieve otherwise unachievable results. ND filters appear gray and reduce the amount of light reaching the film. They have no effect on color balance. This filter offers a filter factor of 0.9, equivalent to 3 stops of light.

Works as general protection filter to reduce dust, moisture, and scratches from reaching lens elements.

HMC multi-coating help to reduce flare, ghosting, and reflections on the filter surface for greater contrast and color fidelity. Greater than 97% light transmission is possible, providing additional contrast and high color fidelity.

Related Questions and Answers

Q: 1. Do these filters have a thread on the front for using a cap?

A: Yes, they are threaded the cap will work

Q: 2. Will these fit my Nikon D3300 with AF-S 18-55 1:3.5-5.6 GII lens as well as 55-200 1:4-5.6 GII ED lens?

A: Ooops. I should have looked before my first answer. It looks like both of your kit lenses have a 52mm diameter, so these filters will work for both without any adapters needed. My first answer still applies, for anyone who has lenses with various thread diameters.

Q: 3. This filter fit in canon sx 50

A: This item requires Canon Filter Adapter FA-DC67A, which is compatible with the SX40, SX50 and SX530. If not available from B&H, try Canon U.S.A. Shop (shop.usa.canon dot com). 67mm filters will then thread on the adapter.

Q: 4. Can I fit a lens cap on it?

A: Yes, a lens cap will fit on these filters.

Q: 5. Is the circular polarizer in this kit comparable at all to the Hoya HD3 circular polarizer in how much light it blocks and color rendering?

A: No, the HD3 is a superior filter.

Q: 6. can this fit on a canon eos m with a 18-55 mm lense?

A: If the 18-55mm lens uses 52mm filters, yes it will fit.

Q: 7. By how many stops of light does the circular polarizer decrease exposure?

A: The following unit will effectively reduce your lens aperture by up to 2 full stops.

Q: 8. Possibly stupid question. Does the circular polarizing filter in this kit rotate? Curious as I'm not sure if they all do that or not.

A: Yes, it does.

Q: 9. Do all the filters have the HMC coating? Only the UV filter is specified.

A: Only the UV filter has HMC coating, however, the circular polarizer and neutral density filter have a single layer coating.

Q: 10. I bouth this item and the 10-18mm Canon lens and I was using the UV with the polarizer attached to it and when looking through the view I see black borders around the image, is this ok? I removed both filters and took the picture again and the black border was not there.

A: That is called vignette. It means that the filters are too thick to be used with that lens and you will get vignette in your images. Chances are if you set the lens to 18mm you might not have vignette. In general it is not a good idea to stack filters so when you use a polarizer you should take off the UV filter. It will reduce the amount of vignette. But with that wide a lens you still might get vignette.
