Pro Glass 72mm HD MC UV Filter for Sigma 18-35mm F1.8 - Protective UV

Our review of the Pro Glass 72mm HD MC UV Filter for Sigma 18-35mm F1.8 finds it to be a practical, no-nonsense protective filter for photographers using that lens. The single biggest reason to buy is simple: it adds a resilient layer of optical glass and blocks ultraviolet light while maintaining image clarity thanks to the multicoated 97% passthrough. For shooters who want lens protection without color cast or heavy glass that alters exposure, this filter serves as a transparent shield and modest quality upgrade over generic clear filters.

Key Features

• Low-Profile Pressed Aluminum Frame: The slim frame reduces vignetting on wide-angle coverage while remaining durable for everyday use.
• Multicoated 97% Passthrough: The coatings maximize light transmission and reduce reflections so the filter does not noticeably darken or color shift images.
• Eliminates UltraViolet Light (UV): Cutting UV helps keep distant haze and blue cast under control in bright outdoor shots without software correction.
• Resilient Optical Glass: The optical glass provides solid protection against scratches and dust while preserving sharpness from the lens.
• Protective Glass UV Filter: Acts primarily as a protective sacrificial element to safeguard the front element of the Sigma 18-35mm F1.8 from impacts and fingerprints.

Who It's For

This filter is best for photographers who own the Sigma 18-35mm F1.8 and want reliable front-element protection with minimal impact on image quality. Landscape, travel, and outdoor portrait shooters who frequently encounter bright daylight or haze will appreciate the UV cut and multicoating.

It is less necessary for studio photographers who control lighting and rarely expose the front element to the elements, or for those seeking specialty effects where a UV-only filter would be insufficient compared with polarizers or neutral density filters.
