These are lenses with the most popular focal lengths, from wide-angle to telephoto, and a variety of apertures. Having one of these is a must for any EOS camera system. Telephoto zoom lenses allow you to capture details normally missed by the eye. Capture the far off action of fast-paced sports or zoom in for an intimate portrait with a blurred background. The unique property of these lenses to compress images allows you to create a variety of impressive images.
This group includes everyday filters which can be left on your lenses, such as Skylight 1B, UV and Polarising. These are the first filters that every photographer should ensure they own. Skylight and UV filters should be constantly fitted to a lens to give improved clarity and color balance as well as offering protection to your lens. Polarising filters have several uses such as ellminating unwanted reflections, increasing color saturation and enhancing contrast.
As their names suggests, these filters use HOYA colored glass. They are used for color correction of different light sources when using color film, or for controlling contrast with Black & White film. Color correction filters are important as color films do not have the flexibility of the human eye to automatically adjust to different situations. Black & White films register colors as shades of grey and the rendition of each color in a scene is important, so filters can be used to control this. The color of the glass used in all these filters is carefully controlled and to reduce the possibility of color shift over a period of time, such high quality filters are coated or multicoated on both sides. This maintains the desired effect and gives a long service life.
