Marumi EXUS Lens Protect Mark II

The Marumi EXUS Mark II Lens Protect is a refined model of our flagship protector. This protection is designed for constant use and offers enhanced security and optical performance, making it ideal for photographers who prioritize both lens safety and image quality.

• Surface reflection rate reduced to 0.2%, down from the original's 0.3% (420-680nm average)
• Certified German-quality glass B270i ensured with a high-precision optical flatness
• High transmittance ascertained more than 99.3% (400-700nm average rate)
• The upmost coating technology implemented; twenty-two layers in total on both sides;
• Anti-static coating (ASC) works wonders on the surface of a glass. Dust and dirt adhered to the surface can be quickly and easily blown off.
• Water-/Oil repellent coating sheds water off simply also by the air blower. Nuisances such as sweat, skin crème, lotion, fingerprint, or compounded grease stains will be wiped off.
  
• Enhanced lens protective function by adapting glass thickness 2.0mm
• Realized a thin frame to avoid vignetting
• Knurling embedded in the lightweight, thin aluminum frame enables easy and smooth handling.
• Made in Japan, optical precision and performance

The defining feature of the EXUS series is its exceptional Anti-Static Coating (ASC). Unlike other filters that merely claim to be dust-free when attached to a lens, the ASC actively repels dust on the filter surface through its antistatic properties. This proven electrostatic prevention effect is what truly sets EXUS apart from other so-called “dust-free” filters.

What is the benefit of using a Lens Protector?
Does it affect image quality? Why Lens Protector instead of UV?

A Lens Protect filter allows you to;
- purely protects your delicate and expensive camera lens from dust, fingerprints, scratches, or, more importantly, from physical shock and damage without affecting image quality.

Many photographers attach a UV filter predominantly in terms of protection. However, a UV filter is designed primarily for UV Protection by optical significance.
It does provide a certain degree of physical protection, such as avoiding scratches in the result. This protective function is contingent on UV Cut.
If your intention is purely to protect your camera and lens from physical damage or mechanical shock, we recommend considering to choose a Lens Protector. 
By all means, UV Protection is also recommendable for Lens Protection. However, it will be more costly to expect the same level of optical benefit with physical protection.
While Lens Protectors provide pure protection, UV filters are used, taking the shooting location and the weather into account.
