Product Description
Advances in high-index / low-dispersion optical glasses, new barrel materials, and exotic anti-reflection coatings, along with the latest in computer-aided-design / computer-aided-manufacturing, are combined to produce filters of unprecedented quality. Nothing changes the way you see the world like High Definition , and no company does High Definition like Opteka. Opteka High Definition Multi-Coated Circular Polarizing Filters create dramatic color for high visual impact. They darken blue skies, saturate colors, and reduce glare and reflections from water or glass by using an Opteka rotating polarizer. Simply look through your viewfinder as you rotate the filter and stop when you reach the desired effect. Ideal for shooting in bright sun, at beaches, snow, etc. The Opteka HD Multi-Coated UV (0) Ultraviolet Haze Filter filter blocks the invisible UV rays which can cause a loss of sharpness. The use of the filter is particularly recommended for work in the mountains, at the ocean, and in areas with very clear air. The contrasts are heightened, and distorting fog is avoided, as this filter cuts haze for sharper black and white prints and corrects the blues and violets in color prints. The filter glass is colorless, and hence no increase in the exposure time is required. This type of filter is also eminently suitable as protection for the front lens, and because of its color-neutral properties it can remain on the camera lens permanently. A scratched front lens element can not be repaired; and replacement is costly. Exchanging a damaged UV filter for a new one is more economical than the purchase of a new lens. Multi-coating can prevent light reflection, ghost light, internal reflection etc, making image clearer and sharper. It can dramatically improve image quality. In the professional setting, Opteka's glass optics define High Definition. Change the way you view the world. Enjoy outstanding detail, enjoy enhanced clarity, enjoy Opteka.
