Night Photography Filter for 49mm Threads

This 49mm circular filter is designed for photographers who shoot at night and need to reduce the warm colour cast caused by artificial light pollution. It uses premium neodymium glass to deliver truer colours and sharper details in astrophotography and urban night scenes. The ultra-slim magnalium rim minimises vignetting on wide-angle lenses. The double-threaded design allows stacking with other filters or a lens cap.

Sustained Optical Performance

The 20-layer nano-coating maintains consistent light transmission and colour balance during long exposures typical of night photography. It resists water, oil and scratches so the glass stays clean through repeated outdoor use. Coating durability prevents degradation that would otherwise shift colour accuracy over time. The neodymium substrate continues cutting the targeted warm wavelengths without adding its own cast.

Compatibility Check Before Ordering

Verify that your lens has a 49mm front filter thread before purchasing. Confirm the ultra-slim rim clears any hood or cap you intend to use without interference. Ensure the double-threaded mount accepts your existing filter stack or lens cap threads. Buyers needing a different thread diameter cannot use this filter without a step-up or step-down adapter.

Questions about this item

Does the 20-layer nano-coating reduce flare or heat buildup during long night exposures?

The coating is designed for higher light transmission and consistent colour balance, not for thermal management; it helps keep images sharp and colours true during extended night sessions.

What thread size must my lens have for this 49mm filter to attach?

Your lens needs a 49mm front filter thread; the filter’s double-threaded rim also lets you stack another 49mm filter or cap on top.

Will the ultra-slim magnalium rim vignette on my older wide-angle lens with a 49mm thread?

The ultra-slim profile is made to minimise vignetting, but very old or extremely wide 49mm-threaded lenses may still show corner darkening at their widest apertures.
