• Heliopan High Transmission Circular Polarizer Filter
• Rotatable Slim Filter Frame (Type 8088)
• Protective Storage Case

The Heliopan High Transmission (HT) Circular Polarizer is a premium, Germany-made lens filter designed for both analogue and digital photography. It eliminates unwanted reflections from non-metallic surfaces like water, glass, and foliage while dramatically boosting color saturation and contrast.

Unlike standard polarizers that cause a heavy light loss of up to 3 stops, the advanced HT technology limits light loss to just 1 to 1.5 stops. Built into an ultra-compact 5.3mm slim profile, it prevents vignetting even when shooting with extreme wide-angle lenses down to 18mm on full-frame sensors.

• High Transmission Technology: Only 1 to 1.5 stops of light loss versus the 3 stops typical of standard filters.
• Vignetting-Free Profile: Ultra-slim 5.3mm socket design eliminates edge shading on extreme wide-angle lenses (18-20mm full frame).
• Reference Scale: Features a rotatable frame with a numeric wreath for precise, repeatable positioning across all camera types.
• Optical Excellence: Constructed with the best German optical glass featuring perfect surface quality.
• True Colors: Ensures color-neutral light attenuation without introducing color casts to your images.
• Refraction Control: Efficiently absorbs scattered atmospheric light and surface glare at a 35-degree angle.
