B+W 49ES 010 UV MRC 49mm (70201BWF)
This filter is a wise initial investment. It helps protect your valuable investment from dust, moisture and scratches, which can lead to costly repairs. If desired it can be left on the lens at all times for protection. A haze filter provides additional benefits of correction for Ultraviolet (UV) light which can register on film and videotape as a bluish cast and can obscure distant details. An ultraviolet filter allows you to correct for the UV effect to varying degrees.
A B+W UV MRC filter is an excellent general purpose filter since it will not only protect your front element from airborne contaminants as well as fingerprints but also help you get better images at high altitude and while on the water. Using this filter will diminish the bluish cast caused by the various atmospheric factors, yet, it will not have an effect on the color balance of your shot. No increase in exposure is required.
The filter ring is made from brass yielding a stronger product. Brass filter rings are also less prone to jamming. In addition, the seal between the glass and filter ring is exceptionally strong giving the filter added strength and durability. The excellent Schott Glass used in the manufacturing of this filter is legendary and synonymous with the highest standards of filter production.
The MRC coating on this filter adds to its durability - particularly under less than optimal weather conditions. In addition, the hard coating makes cleaning the filter easier - especially when it comes to removing fingerprints or surface dirt. Moreover, this filter benefits users of digital cameras whose shorter focal length lenses are more susceptible to dirt and other contaminants on the front lens element.
Multi-coated to minimize reflection at the filter surfaces which reduces flare and ghosting.
