A B&W 77mm XS-Pro Digital NANO Multi-Coated (MRC) Clear #007 Filter is for color as well as black and white photography. It also serves as a permanent lens protector.
The value of a clear filter covering a lens has been well-documented over the years. How many stories have we all heard about photographers dropping lenses and smashing front elements? With a front lens protection filter on, the chances of preserving the valuable glass in your lens increases many fold. Shall we call it a form of inexpensive insurance?
B+W's Multi-Coated (MRC) coating takes filter production to a new level. It features improved cleaning capabilities. Water droplets will bead up better and be easier to remove from the filter. This filter is also scratch-resistant. Single coating is applied to one layer on each glass surface. This improves light transmission from about 92% (uncoated glass) to about 98%. It also has certain anti-reflective properties that help prevent against ghosting and internal flaring.
XS-Pro filters are extra thin but still retain front threads. 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. It comes with a solid 10-year warranty.
The reputation of B+W's Schott glass is world renowned. The high production standards combined with a sturdy brass filter ring make B+W filters hard to beat. These filters have a "heft" to them that is impressive. They may feel heavier but the benefit is in the construction and results. Not only is the glass exceptional but so is the seal between the ring and glass. Schott Glass used in the manufacture of this filter is legendary and synonymous with the highest standards of filter production. It comes with a solid 10-year warranty.
In production, the filter glass is dropped into the empty filter ring from the rear and held in place with a threaded retaining ring; this is a definite advantage over a competitor who uses a spring clip to hold the glass in place. A threaded retaining ring will hold the glass firmly and securely in place to avoid the possibility of rattling and provide perfect paralleling and flatness to your front lens element for ideal optics. The part about additional filters not binding is due to the fact that brass is a very stable metal and does not contract or expand like alloy.
