NiSi Filter ND-Vario 1-5 Stops True Color 49mm

NiSi Filter ND-Vario 1-5 Stops True Color 49mm – Variable ND with True Color and 1–5 Stop Control

The NiSi ND-Vario 1-5 Stops True Color 49mm is a variable neutral density filter designed to reduce exposure by 1 to 5 stops while preserving accurate color. It uses high-definition optical glass and an advanced nano coating to maintain image quality and make cleaning easier.

Stepless, precise density control

You control the ND factor steplessly by rotating the filter. The degree of density changes smoothly as you turn the front ring, allowing fine adjustments without abrupt jumps.

For repeatable settings, the front ring is visually marked with numbers that represent stop values. The ring also features silver side knurlings for a secure grip, making installation and removal easier in the field.

An optional rotating silver lever is included and can be used to help predetermine the additional exposure length required. You can remove the lever if you prefer to operate the ring directly.

Additionally, the filter has built-in hard stops at each end position so you know “where you are” during action use and can quickly return to the end settings when needed.

Designed for both photography and video

This filter suits stills and motion work. Photographers can reduce shutter speeds or open apertures under bright conditions. Likewise, video and cinema shooters can combine aperture and ND adjustments to fine-tune depth of field while retaining a designated frame rate.

Because the ND range is easily adjusted, you can match exposure precisely to the scene and lighting, enabling creative choices—such as larger apertures or longer shutter speeds—that would otherwise be limited by ambient light.

Optical quality, coatings and design

The NiSi ND-Vario uses high-definition optical glass to support the best possible resolution and image quality. The advanced nano coating repels water, grease and dirt, and it also provides anti-reflective properties to help reduce unwanted reflections.

The filter ring is intentionally thin to minimize the risk of vignetting when used on wide-angle lenses. It is made from high-quality aluminum, which provides a strong yet lightweight construction.

The design also aims to avoid the typical “X” effect that can occur with some variable ND filters, delivering a more consistent image across the frame.

Included accessories and mounting guidance

• Includes a front protection cap for the filter.
• Includes a small storage bag to protect the filter when not in use.
• An optional rotating lever is supplied and can be removed if not needed.

For best results, NiSi recommends using this variable ND filter on lenses with a focal length of 35 mm or more on full-frame cameras.

FAQ

Question: How do I change the density on this filter?

Answer: Rotate the front filter ring to change the density steplessly. The ring is marked with numbers to help you set and repeat specific stop values, and you can use the optional lever for extra control.

Question: Will this variable ND cause color shifts in my images?

Answer: The NiSi ND-Vario is specified as a True Color filter and is designed to avoid the color shift commonly seen in other variable filters. It uses high-definition optical glass and coatings to preserve accurate color.

Question: Is the filter suitable for wide-angle lenses?

Answer: The filter has a thin ring and a larger front thread to reduce the risk of vignetting on wider lenses. However, NiSi recommends using a variable ND on lenses with a focal length of 35 mm or more on full-frame cameras for best results.

Question: What comes in the box and can I remove the lever?

Answer: The filter includes a front protection cap and a small storage bag. It also comes with an optional rotating lever that you can remove if you prefer to operate the ring without it.
