Overview

The Tiffen 405UV17 is a 40.5mm UV protection filter designed for photographers and videographers who want to guard their front lens element while gently reducing the effects of ultraviolet light. Classified as UV-17, it absorbs most — but not all — UV radiation, placing it between a clear protective filter and a full Haze 2A cut. The practical result is a subtle reduction in the bluish haze that can appear in outdoor, high-altitude, and coastal shooting, without the stronger warm shift of a heavier UV filter.

Constructed with high-quality optical glass and a metal mounting ring, the filter is built to stay on your lens as a permanent protector. It shields the front element from fingerprints, dust, sand, moisture, and minor impacts — hazards that are far more expensive to fix on a lens than on a replaceable filter. Because the optical glass is designed for high transmission and minimal distortion, the impact on sharpness and contrast is negligible under normal shooting conditions. For photographers using compact lenses with 40.5mm threads — common on mirrorless primes and older rangefinder lenses — the Tiffen UV-17 provides quiet, always-on protection and just enough UV control to keep outdoor images clean.

Pros & Cons

👍 Pros

  • Acts as permanent front-element protection against scratches, dust, and moisture
  • UV-17 coating reduces haze and bluish color cast in outdoor and high-altitude shooting
  • High-quality optical glass maintains image clarity without noticeable degradation
  • Metal mounting ring provides a durable, secure fit that resists cross-threading

👎 Cons

  • 40.5mm size fits only a limited number of lenses; most modern lenses use larger filter threads
  • Adding any filter introduces two additional glass-air surfaces that can increase flare in strong backlight
  • Standard ring profile may vignette on some ultra-wide-angle lenses at this thread size
  • UV-17 absorption level is a niche choice — most shooters opt for a full UV or plain clear protector
