Digital cameras are constantly advancing. Today, models equipped with high-tech features
such as 35mm full-frame digital SLR image sensor are within reach of average consumers.
In other words, the age of high-quality, high-performance digital cameras is here.
The new EXUS Series – the flagship of Marumi digital camera filters
features exceptional performance and functions that are ready to meet and exceed the demands of the latest
digital SLR cameras.

● New Antistatic Coating Repels dust and dirt
● Water & Oil Repellent Water and oil spots can be easily wiped off
● Ultra Low Reflection Less than 0.3%
Blackened outer rim of lens minimizes internal reflections
Key FeaturesEXUS Lens Protect
● Flatness & Strength (Lens) t=2.0mm (Super DHG t=1.3mm)
securely fixed with new slim mount
● New Slim Ultra Low Reflection Frame Light-shielding grooves, satin finish,
knurls on the ring

EXUS LP: Filter Glass
Material: White glass (B270), same as the Super DHG Series
Thickness: 1.3mm ±0.1mm 2.0mm ±0.1mm
Flatness will be stabilized by increasing the lens thickness (precision quality assured).
As pioneered on Marumi’s existing DHG Series, black-ink is coated on the entire outer rim of the lens.
