Large Diameter. Not a widely used size, the Sigma 105mm WR Circular Polarizer is an oversized filter that’s perfect for use with the Sigma 120-300mm f/2.8 DG HSM OS A1 and Sigma 150-600mm f/5-6.3 DG OS HSM Sports.

Reduced Reflections. By simply rotating the filter, you can eliminate reflections from reflective surfaces. Glass, water, eyeballs, the whole lot.

Increased Light Transmission. Sigma’s WR circular polarizers boast of a 30% increase, allowing easier viewing from a viewfinder while intensifying color, tone, and saturation.

Multi-Layer Coatings. This filter is coated to repel water drops and resist smudging from fingerprints and treated to prevent microscopic dust from clinging to the front surface. This helps to ensure sharp images.
