77mm WR Protector Filter

The SIGMA 77mm WR Protector Filter is a circular camera filter designed to shield the front element of a lens. It features water and oil repellent coatings alongside an antistatic layer to resist fingerprints and dust. The colourless glass construction aims to preserve original colour reproduction without affecting exposure. It suits photographers who want a permanent protective barrier for 77mm thread lenses.

Upgrading from basic protectors

This filter replaces standard clear or UV protectors that lack hydrophobic or antistatic treatments. The jump is worthwhile when shooting in humid, coastal, or dusty environments where water droplets, oily smudges, or static-attracted particles frequently degrade image quality. It also benefits users who clean their front glass often and want a surface that releases contaminants more easily.

Outdoor and high-handling shooters

The filter suits landscape, travel, and event photographers who expose lenses to rain, spray, or frequent handling. Studio photographers working in controlled, clean conditions may not need the specialised coatings. Buyers requiring light reduction, colour effects, or polarisation should look at dedicated creative filters instead. Thread size must match the lens exactly at 77mm.

Questions about this item

Does the 77mm thread match my lens filter size?

Yes, the filter uses a standard 77mm thread that screws directly onto any lens with the same diameter.

How do I install it without trapping dust under the glass?

Clean the lens front element first, then screw the filter on gently until snug — over-tightening makes later removal difficult.

Will the water- and oil-repellent coating wear off and need re-application?

The coating is bonded to the glass during manufacture; it cannot be reapplied, so replace the filter if the repellent effect degrades.
