After their very successful Marumi DHG Super line of filters, which have excelled and were top ranked, among the highest quality brands, (read a very well documented and substantiated Polarizing filters test from Lenstip.com) ;

Last April Marumi Optical Co., Ltd. - Japan, introduced in the Japanese market a new line of filters, the “EXUS” Series comprised of the EXUS Lens Protect and EXUS Circular Polarizer, both designed specifically for digital SLR cameras.

These filters are now available in 13 different diameter sizes ranging from 37mm to 82mm, in the overseas markets as well.

Their major feature is a new anti-static anti-reflective coating and glass-mounting system, promising exceptional high-quality imaging in digital SLR photography. Nevertheless, although these filters were developed with the latest digital photography requirements in mind, the EXUS Series filters can also be used on film cameras.

The line comprises of :
EXUS Lens Protect offered in diameters: 37mm, 40.5mm, 43mm, 46mm, 49mm, 52mm, 55mm,58mm, 62mm, 67mm, 72mm, 77mm, 82mm and
EXUS Circular Polarizer offered in diameters: 37mm, 40.5mm, 43mm, 46mm, 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm

The EXUS CPL filters are very low profile, just 4.5 mm high in order to avoid vignetting when installed on wide angle lenses, while they are equipped with light blocking ridges in order to minimize reflections. Less than 0.6% on CPL and less than 0.3% on LP filters. The light transmission of EXUS CPL has increased by 30% compared to conventional polarizing filter.

Both CPL and LP filters are treated with an antistatic coating that inhibits static clinging of microscopic dust. Even if the lens gets soiled, dust can be easily removed using an air-blower.

The innovation in EXUS filter frame, is the adoption of Teflon-coated male threads that not only reduce excessively tight screwing of the filter on the lens, but also makes attaching/detaching smooth and easy
