Overview:
- The Hoya 72mm Digital Filter Kit II includes 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.
UV Filter:
- Absorbs UV light, which can cause outdoor photos to appear hazy and indistinct.
- Clear filter provides no additional coloration or contrast, allowing you to pair this filter with others
- 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.
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.
- Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light
- Clears up haze in distant landscapes and provides more saturated, vivid colors
- Strongest effect when used at a 90° angle from the sun
- Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features
Neutral Density Filter Uses:
- To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars
- To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
- To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situations
- To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure
- 8x = ND 0.9 (exposure adjustment = 3 stops, reduces ISO 1/8)
