UV Protector Filter Compatible with AstrHori 120mm f/2.8 Full-Frame Macro Lens — Blocks UV, Reduces Bluish Daylight Cast, Protects Against Dust & Scratches

Made to fit the AstrHori 120mm f/2.8 Full-Frame Macro Lens, this UV protector filter improves outdoor image quality by absorbing ultraviolet radiation that can create hazy, low-contrast results. It is especially useful in challenging environments such as high altitudes, by the ocean, or in snowy landscapes, where UV can introduce a bluish daylight cast; the filter helps restore more natural tones and clearer detail under these conditions. The filter uses a clear, optically neutral construction with a 1x filter factor (+0 stop), so it does not alter exposure, contrast, or color balance. You retain full sharpness, fine detail, and accurate colors while benefiting from reduced UV influence. Beyond image correction, this filter serves as a daily protective barrier you can leave on the lens. It shields the front element from scratches, dust, dirt, water spots, fingerprints, and accidental contact, and adds an extra layer of defense against bumps, drops, or abrasions — helping extend the usable life of your lens investment.
