Prime II Lens Protect

Marumi Prime II Lens Protect

The Marumi Prime II represents the latest evolution of our lens protection, 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 Cut 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 for their premium lenses.

• Surface reflectance per side reduced to 0.08%*, below 0.1% (420–680nm average, Typical Value)
• Ultra-Low Reflectance Anti-Static (ULA) Coating with thirty-four layers across both sides effectively eliminates ghosting and flare, while allowing dust to be quickly removed with an air blower
  
• The 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 flatness and preserving image integrity
• High transmittance equivalent to EXUS Lens Protect Mark II, while providing a Sharp Cut UV Protection below 380nm
  
• Water-/oil-repellent coating allows sweat, lotion, fingerprints, and grease to be wiped off effortlessly
  
• 2.0 mm thick glass enhances lens protection, while a slim, lightweight aluminum frame helps prevent vignetting
• Made in Japan with exceptional optical precision and performance

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

Ultra-Low Reflectance Anti-Static (ULA) Coating

ULA coating achieves a combination of ultra-low reflectance below 0.1% and highly effective anti-static performance, minimizing ghosting and flare while actively preventing dust from adhering to the filter surface.

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.
