Canon 58mm UV Protector Filter
Canon 58mm UV Protector Filter
The Canon 58mm UV filter is a multi-purpose, fine-weather filter that is designed to optimize your photography experience. Used by many photographers to protect the front element of their lens from abrasions, dust, and moisture.UV filters, absorb ultraviolet rays that often make outdoor photographs hazy and indistinct.
They should be constantly fitted to a lens to provide improved clarity and color balance, as well as to provide additional protection to your lens. UV filters are perfect for digital photography and traditional 35mm SLR applications, including black and white photography.
They also have a very subtle warming effect, which can be useful to counter the "cool" colors you sometimes get in bright sun or in shade.

¦ Fits 58mm lenses
¦ Includes Filter case
¦ Absorbs ultraviolet rays to produce crisp, clear photographs
¦ Ideal for protecting your valuable lens from scratches and dust

Canon EF 50mm f/1.4 USM High Grade Multi-Coated, Multi-Threaded, 3 Piece Lens Filter Kit (58mm) Made By Optics + Nwv Direct Microfiber Cleaning Cloth.
This Item Includes: 1. UV Lens Filter 2. Circular Polarizing Filter 3. Flourescent Filter 4. Filter Pouch 5. Nwv Direct Microfiber Cleaning Cloth. Lens filters are translucent pieces of glass placed in front of a camera lens to alter or adjust the light entering the camera and more importantly to protect the camera lens. Lens filters improve photographs by giving photographers control over light and allowing them to emphasize the features of a scene that they consider most important.This filter kit is a combination of the three essential filters no photographer should be without.UV--Film and a digital CCD are more sensitive to UV light than our eyes are. This often shows up in images shot from high altitudes and long distances especially over water. This filter will remove the UV light and more importantly protect your lens from moisture, scratches, and damage. Circular Polarizer--provides color and contrast enhancement. Reflected light often shows up as a whitish glare that washes out color in an image. A polarizing filter will correct this problem creating deep blue skies. It also removes glare from non-metallic surfaces such as windows and water.FLD--provides color correction when shooting under fluorescent lighting. It will remove the greenish tint from the image, providing pleasing skin tones and true to life color renditions. Warranty:10 year manufacturer warranty. Made in Japan
