UV Protection Filter for Sirui Aurora 85mm f/1.4 Lens — Blocks UV, Reduces Bluish Cast, 1x filter factor (+0 stop), Dust & Scratch Protection

Made specifically for the Sirui Aurora 85mm f/1.4 Lens. This UV filter intercepts ultraviolet rays that can create hazy, low-contrast images—an effect often seen at high elevations, by the sea, or on snowy terrain—so your outdoor photos retain clearer detail and more natural tones by cutting down the bluish daylight cast. Optically neutral and clear, the filter has a 1x filter factor (+0 stop), so it leaves exposure, contrast and color balance unchanged. It preserves the lens’s sharpness, fine detail and true color accuracy while still providing UV reduction, meaning no corrective adjustments are needed to maintain image quality. Intended for continual use, the filter doubles as a protective barrier for the front element. It helps guard against scratches, dust, dirt, water spots, fingerprints and accidental contact, and adds extra resistance to bumps, drops and abrasions—helping extend the life of your lens investment.
