Product Description
-------------------
This UV Filter blocks the invisible UV component of light from
the sky, which can cause blur and to which many color films react
with a blue cast. These filters should be called UV-Blocking
Filters, because there are filters for technical applications
that pass UV radiation and block all the other wavelengths.
Nevertheless, the short term "UV Filter" has become established
among photographers. UV Filters are ideal for photography in high
altitudes (in the ains), by the sea and in regions with very
clean air. The pictures gain brilliance and disturbing blue casts
are avoided. Because the glass is colorless, color rendition is
not altered, aside from the elimination of the unwanted blue
cast, and no increase in exposure is required. That makes a UV
Filter very suitable as protection of the front element of the
taking lens against dust, flying sand, sea water spray and the
like, and it can be kept on the lens at all times. It is
recommended for analog color and black-and-white as well as
digital photography.

B+W's Superior MRC Coating with Nano Technology
-----------------------------------------------
Illustration of lotus effect on water
droplet caused by nano coating. The nano coating is an outer
layer of protection that comes standard with all XS-Pro Digital
MRC filters. The nanotechnology based characteristic (lotus
effect) produces a better beading effect with water, making the
cleaning of this filter even simpler and faster than ever before.
MRC nano has an improved outer (8th) layer over regular MRC.
The lens elements of high-quality lenses and the plano surfaces
of filters require a perfect shape and smoothness to achieve the
best optical quality. Dirt, greasy fingerprints, water marks and
scratches reduce the image contrast and the sharpness, which can
result in blooming at light sources and have an effect similar to
a soft-focus lens. A clean front lens element and clean filter
surfaces are therefore an absolute pre-requisite for demanding
photographers.
The nano coating results in lotus effect on water droplet. The
MRC coating is first and foremost a broadband anti-reflection
coating. This means that its reflection-reducing effect, which is
thus also a transmission-increasing effect, i.e. one which
suppresses scattered light and ghost images and transmits more
light, has a broadband action over the full spectrum. In
contrast, the (almost always blue) single-layer coating only has
a high effect in the medium wavelength range around yellow and
yellow-green where the eye is most sensitive to light, while its
effect is greatly reduced toward the blue-violet and purple-red
end regions of the visible spectrum. With the MRC coating, this
blue, violet and red to deep-red light cannot produce any
contrast reducing scattered light, spotty reflections or ghost
images. A broadband effect can only be achieved with a multilayer
coating which requires a much higher effort and precision because
unevenness and irregularities of the individual layers build up
on one another and amplify one another. Schneider therefore uses
a plasma-assisted evaporation coating process in which inert
ions accelerated in an electrical field compact the material
deposited on the lens surface in the vacuum chamber.
For photographers, the main advantage of MRC coating, is it's
ability to combat flare and ghosting. An added benefit is that
their filters remain free of dirt longer, so that they do not
have to be cleaned so often. When cleaning the filter does become
necessary, it is a lot easier to wipe off the dirt with a blower
brush, because of MRC's ability to repel dirt and moisture. This
also reduces the risk of micro-scratches which can occur during
cleaning.

XS-Pro Digital Filter
---------------------------
This filter uses our XS-Pro Digital which is especially
suited for DSLRs with wide angle and zoom lenses. It has a front
thread for additional accessories such as lens caps or hoods. All
XS-Pro Digital s are made of brass and are matte black to
prevent reflections.
- PROTECT YOUR EXPENSIVE CAMERA LENSES - The B + W 49 mm UV haze clear camera filter is here to add 16 multi-resistant nano-coating layers of protection against accidental drops, dust, flying, fingerprints, dirt, scratches sand or seawater spray. Enjoy outdoor photography without worrying about your precious lenses anymore..
- TAKE BLUE CAST OUT OF THE PICTURE - Literally. Whether you are a professional photographer or a beginner, the invisible Ultra-Violet component of light from the sky is a common issue. Our UV-blocking haze protector filter for 77mm lenses will eliminate blue cast and help you snap clearer images..
- XS-PRO - Thanks to precise precision manufacturing, B+W sockets fit absolutely accurately and are easy to install. The 49mm narrow XS-PRO will eliminate vignetting in most cases, even at high wide-angle s. The internal thread means that a conventional lens hood can also be fitted..
- CHOOSE YOUR SIZE – To select the appropriate filter size, check your lens. On all lenses from Canon, Nikon, Olympus, Samsung, Fuji and other manufacturers there is a printed diameter symbol that determines the filter size..
- MADE IN GERMANY - Schneider Kreuznach (B + W) – We are proudly your precision mechanics spets for filters, photography, optics and precision, with more than 100 years of German experience. Schneider products have already been used in NASA's Apollo missions. Thanks to our multi-resistant nano coating lens filter, we are helping photographers everywhere take clearer, crisper images..
