We are delighted to introduce Sigma's new, high quality, low price screw-in filters - this particular one is water and oil resistant.
The UV is a colourless glass filter that absorbs ultraviolet rays, hence the bluish cast that occurs in sunny weather (at high colour temperatures, i.e. above 6500 K).
It is also the ideal filter to leave on the lens permanently as a lens protector.
