B+W 77mm Basic Circular Polarizer MRC Glass Filter - Controls

In this review the B+W 77mm BASIC MRC Circular Polarizer is evaluated for everyday photographers who want reliable polarization without fuss. The bottom line: it is a straightforward, well-built polarizer that removes reflections from non-metallic surfaces and boosts color saturation, with a knurled mount that makes adjustments easy. Our review finds it especially useful for landscape and travel shooters using lenses down to 24mm full frame, and the included QR code and MRC coating are practical touches for quality and flare control.

Key Features

• Black Knurled Filter Mount: Provides a firmer grip for precise rotation so photographers can quickly dial in the polarization effect even when working in the field.
• MRC Coating: Reduces flare and ghosting under strong light sources, which helps maintain contrast and clarity in high-contrast scenes.
• Rotating Mount: Allows continuous control of polarization so reflections on water, glass, and glossy paint can be reduced to reveal details behind surfaces.
• 24mm Full Frame Coverage: Optimized to work without significant vignetting on lenses down to 24mm, making it suitable for wide-angle landscapes.
• QR Code Authenticity: The new QR code helps confirm the filter is genuine, giving buyers confidence in construction and coatings.
• ECO-Friendly Packaging: Uses reduced packaging materials which is a small environmental benefit for frequent buyers of accessories.

Who It's For

The B+W 77mm polarizer is aimed at enthusiasts and professionals who already own lenses with a 77mm thread and need dependable polarization for outdoor and street photography. It suits landscape shooters who want improved color saturation and contrast, and portrait or product shooters who need to control reflections on non-metallic surfaces.

Photographers using lenses wider than 24mm on full frame or those who require specialized multi-layer coatings beyond basic MRC should consider higher-end or slim-profile polarizers, but for most everyday use this filter balances build quality and practicality.
