B+W 77mm Master High Transmission Kaesemann Circular Polarizer

In this review the B+W 77mm MASTER High Transmission Kaesemann Circular Polarizer is evaluated for landscape and travel shooters who need reliable polarization without heavy light loss. The bottom line: this filter delivers accurate reflection control and improved color saturation while preserving more light than many polarizers, making it well suited to handheld work and lenses that must maintain autofocus. Its rotating mount and thin knurled frame make adjustments easy in the field, and the high transmission MRC coating helps control flare and ghosting for cleaner images.

Key Features

• Thin knurled mount: the black knurled thin profile filter mount gives a better grip and reduces vignetting on wide-angle lenses down to 17mm full frame.
• MRC coating: multi-resistant coating controls flare and ghosting so highlights remain cleaner in backlit scenes.
• High transmission design: the MASTER High Transmission element passes more light than typical polarizers, equivalent to about 1 to 1.5 f-stops, which helps preserve exposure and autofocus performance.
• Rotating polarizer: a smooth rotating mount lets the photographer dial in polarization precisely to reduce reflections from water and glass and increase color saturation.
• Authentication QR code: the included QR code allows verification of authenticity for buyers who want assurance of genuine B+W quality.
• Eco-friendly packaging: shipped in environmentally conscious packaging that reduces waste without compromising protection.

Who It's For

This filter is best for landscape, travel, and architectural photographers who frequently encounter reflective surfaces and want stronger color saturation without losing valuable light. Its good light transmission makes it a practical choice for shooters who rely on autofocus and handheld exposure in changing light.

Photographers who need extreme light reduction or variable ND functionality should look elsewhere, and those using lenses wider than 17mm full frame should confirm fit and potential vignetting before purchase.

Pros & Cons

Pros

• Excellent control of reflections and improved color saturation with minimal light loss.
• Thin knurled mount gives positive grip and lowers the risk of vignetting on wide-angle lenses.
• MRC coating reduces flare and ghosting for cleaner images in challenging light.
• Included QR code for authenticity provides confidence in purchase.

Cons

• Transmission is improved but still introduces about 1 to 1.5 f-stops of light loss, which may matter in very low light.
