UV Protector Filter for Pentax smc FA 645 200mm f/4 IF Lens — Neutral 1x (+0) UV Shield, Reduces Blue Daylight Cast, Prevents Dust & Scratches

Made for the Pentax smc FA 645 200mm f/4 IF Lens, this UV protector absorbs ultraviolet light that can cause hazy, low-contrast images—most noticeable at high altitudes, by the ocean, or in snowy environments. By cutting the bluish daylight cast, it helps deliver more natural tones and improved clarity across varied outdoor lighting conditions. The glass is optically neutral and clear with a 1x filter factor (+0 stop), so it does not affect exposure, contrast, or color balance. Your photos retain full sharpness, detail and accurate color reproduction while still benefitting from UV reduction. Built to serve as a permanent front-element safeguard, the filter can remain on the lens during everyday use to block scratches, dust, dirt, water spots and fingerprints and to prevent accidental contact with the front element. It also adds protection against drops, bumps and abrasions, helping extend the usable life of your lens investment.
