Sigma 77mm WR UV Filter
Description
Sigma's weather-resistant (WR) ultra-violet (UV) filters prevent the bluish tone that generates when the weather is fine, by absorbing ultraviolet rays. It is effective in most situations, such as landscape, portrait and general photography on a sunny day. It is also an ideal filter for regular use as it is completely colourless so does not affect colour reproduction. With excellent water and oil repellent functions, the filter surface repels water drops and provides resistance to fingerprints. Even if they appear on the surface they can be easily removed.
