• Ultra-High Definition Image Quality: Crafted from premium Japanese AGC optical glass and precision polished for strict flatness and 100% concentricity.

This ultra-low reflection technology maintains high contrast and true color accuracy, making it an essential UV filter for landscape, portrait, and architectural shooting.

Unlike standard aluminum frames, this heavy-duty brass construction prevents jamming, binding, and cross-threading, ensuring reliable installation and removal in fast-paced shooting scenarios.
• Exact 77mm Thread Compatibility: Specifically designed to fit any camera lens with a 77mm front filter thread. Please verify your camera's lens thread size (marked by the "Ø" symbol on the lens barrel) before purchasing. The refined profile securely accommodates original lens caps without adding excess bulk.
