Rollei Astroklar Light Pollution Filter 72mm - Clear Night Contrast

In this review the Rollei Astroklar Light Pollution Round Filter (72mm) is assessed for photographers who shoot nightscapes and urban astrophotography and need cleaner, higher-contrast images without complex post-processing. The bottom line: this filter is for users who want a simple, optical way to reduce the glow of artificial lights while preserving scene tonal balance. The reviewer found the filter easy to use on lenses with a 72mm thread, noticeably reduces sodium/vapor glow, and keeps image tones neutral in the infrared range when white balance is managed manually.

Key Features

• Light pollution reduction: Reduces unwanted glow from artificial street and building lights to improve contrast in night and astrophotography scenes.
• High-quality optical glass: Construction from optical glass provides clear, sharp rendering without obvious softening across the frame.
• Double-sided Nano coating: The water repellent coating keeps the surface clearer in damp conditions and makes cleaning easier after field use.
• Anti-reflection and repellency: Prevents reflections and resists water, oil and dirt to maintain consistent performance in varied shooting situations.
• Neutral infrared behaviour: Acts neutrally within the infrared range so it does not introduce unexpected colour shifts in long exposures.
• Included accessories: The box contains one Astroklar filter and an information manual for quick setup and white balance guidance.

Who It's For

The Rollei Astroklar 72mm is best for intermediate and advanced photographers who capture cityscapes, architectural night scenes, or urban astrophotography and want to reduce light pollution optically rather than rely solely on editing. It suits photographers who use manual white balance and are comfortable adjusting colour temperature to counter the filter's slight cooling effect.

It is less relevant for photographers who rarely shoot at night, who primarily photograph deep-sky objects far from city light sources, or who need filters for other specialised spectral bands. Users seeking an all-in-one automatic colour correction may prefer a different workflow because the filter recommends manual white balance adjustments.

Pros & Cons

Pros

• Effectively reduces urban light pollution to improve perceived contrast in night images.
• Quality optical glass and double-sided Nano coating keep images sharp and make cleaning straightforward.
• Neutral behaviour in the infrared range avoids unwanted IR-induced colour shifts during long exposures.

Cons

• Introduces a slightly cooler tone that requires manual white balance adjustments for accurate colour reproduction.

Frequently Asked Questions

Will this filter work on any lens?
The filter fits lenses with a 72mm thread; confirm your lens filter size before purchase.

Does it change colour balance?
Yes, the coating gives a slightly cooler tone so the manufacturer recommends using manual white balance and adjusting between +700K and +1,500K if needed.

Is the surface easy to clean in the field?
The double-sided Nano coating repels water, oil and dirt and makes cleaning the glass straightforward after outdoor use.
