Rollei Astroklar 67mm Light Pollution Round Filter - Clear Night

Our review of the Rollei Astroklar Round Filter finds it to be a focused accessory for photographers who shoot nights in urban or suburban areas and need cleaner contrast without complex post processing. The single biggest reason to buy is its optical glass construction combined with a double-sided nano coating that actively reduces common light pollution effects from street and building lighting while staying neutral in the infrared range. For anyone shooting cityscapes, architecture at night or backyard astrophotography, it offers a pragmatic way to improve clarity and contrast in-camera.

Key Features

• Light pollution reduction: Reduces unwanted artificial skyglow so stars and distant details appear with greater contrast and definition in night scenes.
• Optical glass construction: Manufactured from high-quality optical glass to preserve image sharpness and avoid introducing aberrations.
• Double-sided nano coating: Water, oil and dirt-repellent surfaces help keep the filter clear in wet or dusty shooting conditions and make cleaning easier.
• Reflection control: The special coating prevents reflections that can otherwise degrade night exposures when using bright street or building lights.
• Infrared neutrality: Neutral behaviour within the infrared light range helps avoid unwanted color shifts in long exposures.
• Included information manual: The box contains one Astroklar filter and a manual to help set white balance and get expected color tone results.

Who It's For

The Astroklar filter is best for photographers who regularly shoot night scenes in areas affected by artificial lighting and want a simple in-camera tool to boost contrast without heavy editing. It suits cityscape and architectural night shooters as well as hobby astrophotographers working from light-polluted locations.

It may not be necessary for photographers who already work from very dark sky sites or those relying entirely on software-based light pollution removal; those users should consider whether the small tonal shift and manual white balance recommendation fit their workflow.

Pros & Cons

Pros

• Effectively reduces light pollution effects, improving perceived contrast in night images.
• High-quality optical glass maintains sharpness and image quality through the filter.
• Durable double-sided nano coating repels water, oil and dirt and reduces reflections.
• Neutral infrared behaviour avoids unexpected color bias in long exposures.

Cons

• Produces a slightly cooler tone, so manual white balance adjustment is recommended for accurate colors.
• Benefits are most noticeable in light-polluted environments and less useful for very dark-sky shooting.

Frequently Asked Questions

Will this filter remove all light pollution?
The filter reduces many common artificial skyglow effects but does not eliminate all light pollution; results depend on the intensity of local lighting.

Do I need to change white balance?
Yes, the coating tends to give a slightly cooler tone, so using manual white balance (approximately +700K to +1,500K) is recommended.

What is included in the box?
The package contains one Astroklar round filter and an information manual to guide setup and white balance choices.
