By far the most important accessory you can
buy for your professional camera lens is a
high quality filter. B+W filters are valued by
professional photographers for their exquisite
optical quality and fine multicoatings. B+W
is a must have for every pro quality lens.
Ultraviolet light, which manifests itself in photographs as reduced
clarity and the appearance of haze, is blocked by the UV 010.
Ultraviolet light is invisible to the eye and is strong in mountainous
and coastal areas with very clear air. This makes the colorless UV 010
an indispensable filter because it requires no exposure compensation.
It is recommended as an ideal filter to be kept permanently on the lens
to protect the front element. Filter factor is 1.0.
