The
Digital Filter Kit from
Hoya offers everything you need to get started with your outdoor shooting.
UV Filter
UV
filters are wise initial investments. They help protect your valuable
investment from dust, moisture and scratches, which can lead to costly
repairs. This filter is multi-coated.
Circular Polarizer Filter
Light
rays which are reflected become polarized. Polarizing filters are used
to select which light rays enter your camera lens. They can remove
unwanted reflections from non-metallic surfaces such as water or glass
and also saturate colors providing better contrast. The effect can be
seen through the viewfinder and changed by rotating the filter. The
filter factor varies according to how the filter is rotated and its
orientation to the sun.
Neutral Density Filter
Neutral
Density filters have several uses and offer the possibility to achieve
otherwise unachievable results. They enable the shooter to adjust
exposure without affecting color balance. ND filters appear gray and
reduce the amount of light reaching the film.
Determining which
neutral density filter yields ideal results for any given lighting
situation takes knowledge, experience and a collection of such filters.
Speaking generally, the 2-stop value (ND 4x) effectively compensates
average situations.
Hoya is one of the largest manufacturers of
glass in the filter industry. In collaboration with its parent company,
Tokina Optical, Hoya continues to strive to produce some of the best
glass on the market. Currently, they hold 40% of the world's market for
optical glass.
The kit comes with a handy filter pouch in which your filters will be safely guarded and that will fit within your gear bag.
Note! Circular polarizers are
specifically designed for use with auto-focus SLR cameras (They will
also work on manual systems and video cameras without problems)
UV Filter
-
Hoya filters provide additional benefits of correction for
Ultraviolet(UV) light which can register on film and videotape as a
bluish cast and can obscure distant details
-
If desired they can be left on the lens at all times for protection
Circular Polarizer
-
This filter eliminates ultraviolet rays to remove haze from
outdoor shots as well as polarizing the light to remove reflections, and
increase color saturation, without affecting the overall color balance
Neutral Density Filters Have Four Main 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
Neutral Density Factors
-
2x = ND.3 (exposure adjustment = 1 stop, reduces ISO by 1/2)
-
4x = ND.6 (exposure adjustment = 2 stops, reduces ISO by 1/4)
-
8x = ND.9 (exposure adjustment = 3 stops, reduces ISO by 1/8)
Hoya Quality
-
As one of the premier filter manufacturers, Hoya filters
continue to made from quality glass assuring the photographer clear,
sharp and accurate images
-
Hoya filters consistently provide even color all the way through
the filter; all surfaces are ground and polished to specific thickness
and tolerances
-
Even non-multi-coated Hoya filters have one layer of
anti-reflective coating applied to each surface of the glass; Hoya's
single layer coating decreases light reflection off the surface from
approx. 9% to an average of 4-5%
