Prime II Lens Protect

Marumi Prime II Lens Protect

The Marumi Prime II represents the latest evolution of our protection milestone, built on decades of specialized expertise. This new flagship achieves a breakthrough that was once thought technically hard to balance: the seamless integration of world-leading 0.08% ultra-low reflectance and advanced anti-static performance, while also providing effective Sharp UV protection. It stands as the highest achievement of our current optical path of frontier—a new milestone for photographers who require uncompromising image integrity.

• Surface reflectance reduced down to 0.08%, surpassing 0.1% barrier to achieve the ultimate protection value (420-680nm average, Typical Value)
• Advanced multi-coating with thirty-four layers total on both sides effectively eliminates ghosting and flare
  
• The newly redesigned frame reduces vertical surface height and adds light-blocking ridges to eliminate internal reflections
• Made from Japanese Ohara S-BSL7, equivalent to Schott BK-7, ensuring high-precision optical flatness and preserving image integrity
• High transmittance equivalent to EXUS Lens Protect Mark II, also providing Sharp Cut UV Protection below 380nm
  
• Anti-Static Coating (ASC) seamlessly integrates with ultra-low reflectance, allowing dust to be easily removed with an air blower
• Water-/oil-repellent coating makes sweat, lotion, fingerprints, and grease wipe off effortlessly
  
• Glass thickness of 2.0mm enables enhanced lens protection, while simultaneously realizing a thin frame to avoid vignetting
  
• Lightweight and thin aluminum frame
• Made in Japan with exceptional optical precision and performance

*Verified by factory spectrophotometer measurements. Details review in "TECHNICAL DATA".

Anti-Static Coating (ASC)

The defining feature of the EXUS series is its exceptional Anti-Static Coating (ASC). Unlike standard filters, ASC actively repels dust on the filter surface through proven antistatic properties. 

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

A Lens Protector purely protects your delicate and expensive camera lens from dust, fingerprints, scratches —and most importantly—physical shock and impact, without compromising image quality.

Many photographers use UV filters primarily for protection. However, UV filters are designed mainly for ultraviolet light blocking. They do provide some physical protection, but this is secondary to their UV-cutting function. 

If your goal is purely physical protection against damage and shock, we recommend a Lens Protector. UV protection is valuable for lens safety in certain conditions. However, achieving equivalent optical performance and physical protection with a UV filter is more costly. UV filters are chosen based on shooting location and weather conditions.
