Once again, wit normal single-layer coatings the loss of transmission for both surfaces on average amounts to only approximately 3%, whereas with more complex multiple coatings (MC) it amounts to a mere 0.5%. A more significant aspect than the gain in light transmission is the reduction of reflections and ghost images to about 1/3 with simple coating, and to less than 1/16 with MC coatings.
MRC coating (Multi-Resistant Coating) by B+W is not only an extraordinarily effective multiple layer coating, it is also harder than glass, so that it protects filters from scratches (for instance when cleaning the filters), and it is also water- and dirt repellent, thus facilitation filter maintenance.
010 means UV filter
F-Pro means for compact basic holder for standard and polarizing filters
B+W Standard Filter Mount F-Fro
Compared to the earlier B+W standard filter mount, the B+W Standard Filter Mount F-Pro has been improved considerably.
While maintaining the excellent quality of materials, fabrication and high mechanical stability, the new F-Pro mount has become thinner, so that now it can also be used on many wide-angle lenses without the danger of vignetting. An exact focal length limitation cannot be stated, because vignetting depends not only one the height of the filter mount, but also on the design of the front of the lens. Nevertheless, the following can serve as a guide: The B+W standard filter mount F-Pro can be used without vignetting on 35mm camera lenses with focal lengths of 35mm, most 28mm lenses, and in many cases even on 24mm lenses.
Another advantage of the new F-Pro filter mount is its modified retaining ring, which is no longer threaded in from the front, but holds the filter glass in place from the back. This prevents the retaining ring from being accidentally loosened during the removal of an additional filter or a lens hood that has been screwed in too tightly.
Not entirely sure what ES means
there is such a thing as ESW though...
