The classic redefined: More light, more energy

The 82CIRG Ruby Grapefruit is the logical evolution of the legendary Grapefruit profile. Inspired by the groundbreaking science behind the 2025 Watermelon glass, the Ruby Grapefruit takes high light transmission performance to a new level.

With a transmittance of 82%, this lens is designed for situations where every ounce of residual light counts – be it in deep twilight, on heavily overcast days, or in dark forest stands. Despite the high light transmission, the refined Chromashift Infrared technology provides a noticeable contrast boost ("bump") that effectively "wakes up" the eye and separates the target with razor-sharp clarity from the background.

The highlights of the 82CIRG Ruby Grapefruit:

• Next-Gen Grapefruit: The modern answer to the classic grapefruit filter – scientifically optimized for 2026.
• Watermelon DNA: Utilizes the advanced filter science of the 2025 Watermelon series for even clearer color separation.
• Maximum brightness: 82% light transmission guarantees an extremely bright image without losing control over the color profile.
• Visual kick: The lens was designed to “excite the eye” – this means faster focus and less visual fatigue in low light.
• Expert tip: “Anyone who liked the old grapefruit lens will love the 82CIRG. It has exactly that extra ‘punch’ in brightness and sharpness that we always wanted in low light. It’s the perfect ‘bad weather lens’ with the soul of a high-performance filter.”
