UV Protection Filter for IRIX 45mm f/1.4 K — Optically Neutral 1x (+0 Stop), Reduces Bluish Daylight, Anti-Scratch/Dust Shield

Made specifically for the IRIX 45mm f/1.4 K, this UV protector filter blocks ultraviolet radiation that can introduce haze and lower contrast in outdoor shots. It is especially helpful in high-altitude environments, by the sea, or in snowy settings where UV-induced bluish casts are most noticeable, yielding more natural color rendition and clearer results in varied lighting. The filter is optically neutral with a 1x filter factor (+0 stop), so it leaves exposure, contrast and color balance unchanged. Because it does not alter image sharpness or detail, you retain the original fidelity of your photos while benefiting from reduced ultraviolet influence. Beyond image correction, the glass serves as a daily protective barrier for the front element of your lens. Keep it mounted to safeguard against scratches, dust, dirt, water spots and fingerprints, and to provide added protection from minor bumps or drops—helping preserve your lens and extend its service life.
