Product Information
Full details
The Sigma 72mm WR Protector Lens Filter is designed for photographers seeking reliable protection for their camera lenses against everyday hazards like dirt, dust, and scratches. Its primary benefit is robust defense without compromising image quality, as it is completely colorless. A potential caveat is its specific 72mm size, requiring a matching lens thread. This filter features water and oil repellency, antistatic properties to deter dust, and Sigma's Super Multi-Layer Coating to minimize flare and ghosting, making it an excellent choice for consistent use on both digital and film cameras.

FAQs
What is the main purpose of the Sigma 72mm WR Protector filter?
Its main purpose is to protect the front element of your camera lens from scratches, dust, and dirt, while also offering water and oil repellency and reducing flare.
Will this filter affect the colors in my photos?
No, the Sigma WR Protector filter is completely colorless and designed not to affect color reproduction, ensuring that your images retain their original color accuracy.
How do I clean the filter effectively?
Use a clean microfiber lens cloth for regular dusting. For fingerprints or smudges, lightly dampen the cloth with a dedicated lens cleaning solution and wipe gently.
Can I use this filter on any lens?
This filter is specifically designed for lenses with a 72mm filter thread size. You must confirm your lens's filter diameter before purchase.
What does 'WR' stand for in the filter name?
WR stands for Water & Oil Repellent, highlighting one of the key protective features of the filter's surface coating.
Does the filter reduce flare and ghosting?
Yes, it features Sigma's Super Multi-Layer Coating, which is designed to reduce unwanted flare and ghosting, especially when shooting towards bright light sources.
Is this filter suitable for wide-angle lenses?
The filter is designed to avoid vignetting, especially on Sigma lenses. However, on extremely wide-angle lenses, any filter can potentially cause slight light reduction at the edges. It's always best to test on your specific lens if this is a concern.
Troubleshooting
Filter is difficult to screw onto the lens.
Ensure you are using a lens with a 72mm filter thread. Check for any debris on the lens threads or filter threads. Try to thread it on straight without cross-threading.
Image appears hazy or has excessive flare.
Clean the filter surface thoroughly with a microfiber cloth. Ensure the filter is correctly seated and not damaged. Check if shooting directly into a strong light source is the cause.
Water spots remain on the filter.
While the filter is water-repellent, heavy water exposure may still leave residue. Clean gently with a lens cleaning solution and a microfiber cloth.
Dust seems to cling more than expected.
The antistatic properties reduce dust, but do not eliminate it entirely in extremely dusty conditions. Clean the filter regularly with a microfiber cloth.
Pros and Cons

- Repels water and oil, simplifying cleaning and maintenance.
- Antistatic properties help keep the filter free from dust.
- Reduces lens flare and ghosting for clearer images.
Cons
- Limited to lenses with a 72mm filter thread; not universally compatible.

Setup, Compatibility & Care
Setup:
To attach the Sigma 72mm WR Protector filter, simply align the filter's internal threads with the external threads on the front of your 72mm lens. Gently screw the filter on clockwise until it is snug. Do not overtighten. To remove, reverse the process by gently unscrewing it counter-clockwise.
Compatibility:
This filter is designed for camera lenses with a 72mm filter thread diameter. Always confirm your lens's filter size before purchasing. It is compatible with both digital and film cameras. The design is optimized for Sigma lenses to avoid vignetting, but it can be used with other brands of lenses with the same 72mm thread size.
Care:
Keep the filter clean for optimal performance. For general cleaning, use a soft microfiber lens cloth to wipe away dust and smudges. For more stubborn marks, such as fingerprints or water spots, lightly dampen the cloth with a lens cleaning solution. Avoid using abrasive materials or harsh chemicals, as they can damage the coatings. Store the filter in its protective case when not in use to prevent scratches.
