Combining two of the most useful filters available, Luminesque's 77mm Circular Polarizer and UV Slim PRO Filter Kit is well-suited to all forms of photography. Both filters are constructed from Schott optical glass and feature a 12-layer multi-coating for maintained clarity and image quality. Each filter is also set in an anodized aluminum filter ring, with the UV filter featuring a slim 3.4mm-thick profile to lessen the likelihood of vignetting with wide-angle lenses.
The UV filter is a general use, clear filter that helps to absorb ultraviolet light and reduce the bluish cast of daylight. It is also useful as a general protective filter to leave on lenses at all times in order to reduce dust and moisture from reaching the front lens element and to provide additional protection in case of accidental impacts. Its 12-layer multi-coating also helps to achieve 98.2% light transmission for faithful color reproduction and contrast.
The 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. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera's autofocus and auto exposure functions.
Keep your optical surfaces clean with the Sensei Optics Care and Cleaning Kit. This kit contains a pack of lens tissues, a lens cleaning pen, a bulb air blower, a paint brush, a lipstick brush, lens cleaning fluid, and a see-through mesh travel case to put everything in. This kit can be used to clean a variety of different optics and glass. You can use the air bulb blower and any of the three supplied brushes to initially remove dust from the surface. Sensei recommends applying a small amount of the alcohol- and ammonia-free cleaning fluid directly to the lens tissue. Then, gently rub in small circular motions to remove stubborn smudges or fingerprints from the glass. For those more stubborn blemishes or smudges, the lens pen is very effective.
