Sonia Filter MCUV-55 mm

Uncovered camera lens has to be cleaned again and again, its coating is wiped off, polish diminishes and lens becomes soft and blurred. Primarily used as a lens protection filter, absorbs the ultraviolet rays which often makes outdoor photography hazy and indistinct. A multipurpose all weather filter for color as well as black and white photography. Exposure compensation not required. Difference between Un-Coated and Multi-Coated Filters: Glass does not transmit all vol of light, some portion of the light is reflected by the glass itself and the remaining transmits through it, thus resulting in loss of some portion of the light. To improve the rate of transmission, thin-film coatings are applied on the glass surface suitable for wave length of each color. Whereas, the loss of light in uncoated filter is 8%, the same is about 4% in 4 layer coating. The Multi-Coating helps to suppress reflections which reduces flare and ghosting and increases light transmission.
