NiSi Filter ND-Vario 1-5 Stops True Color 40.5mm

NiSi Filter ND-Vario 1-5 Stops True Color 40.5mm – Variable Neutral Density with True Color Rendition

The NiSi ND-VARIO 1-5 Stops True Color 40.5mm is a variable neutral density filter that reduces exposure by 1 to 5 stops while maintaining accurate color reproduction. It uses high-definition optical glass and a True Color design to avoid the color shifts commonly seen in other variable ND filters.

Key benefits and intended use

Use this filter for both photography and video to precisely control the light entering your lens. You can lower shutter speeds or open the aperture while keeping your chosen frame rate. For cinema and video work, combine aperture adjustments with this filter to fine-tune depth of field without changing exposure settings or frame rate.

Control, handling and markings

The density is stepless and you control it by rotating the filter. The front ring is visually marked with numbers that represent different stop values, which makes repeatable adjustments easier. Additionally, the ring has silver side knurlings for a secure grip and simpler installation and removal.

The filter includes hard stops at each end of the rotation, so you can quickly know the end positions during action use. You may use the included silver rotating lever for easier adjustments, and you can remove it if you prefer to operate the ring without the lever.

Optical and build features

This NiSi filter uses high-definition optical glass for clear resolution. It features an advanced nano coating that repels water, grease, and dirt, which also makes the surface easier to clean. The filter ring is thin to minimize the risk of vignetting on wide-angle lenses, and it is constructed from high-quality aluminum to remain light yet strong.

Practical accessories and recommendations

The filter comes with front protection and a small storage bag. For best results, NiSi recommends using a variable ND filter on lenses with a focal length of 35 mm or more (full frame).

FAQ

Question: Does this filter cause color shifts in my images?
Answer: No. The NiSi ND-VARIO True Color design uses high-definition optical glass to avoid the color shift seen in other variable filters, delivering more accurate color reproduction for both stills and video.

Question: What exposure control does this filter provide?
Answer: The filter offers a variable ND range of 0.3 to 1.5 (which corresponds to an exposure reduction of 1 to 5 stops). You adjust the density steplessly by rotating the front ring, and the ring features marked stop values for repeatable settings.

Question: Is the rotating lever included and required?
Answer: The package includes a silver rotating lever that simplifies density adjustments, but you can use the filter with or without the lever. The lever is removable if you prefer direct ring operation.

Question: Will the filter cause vignetting on wide-angle lenses?
Answer: The filter uses a thin ring design and a larger front thread to reduce the risk of vignetting on wider lenses, and it is recommended for lenses of 35 mm focal length or more (full frame) for optimal results.

Question: How does the coating help in practical use?
Answer: An advanced nano coating repels water, grease, and dirt, which helps keep the surface cleaner and makes it simpler to maintain during field use.
