NiSi Filter ND-Vario 1-5 Stops True Color 55mm

NiSi Filter ND-Vario 1-5 Stops True Color 55mm – True Color Variable ND for Controlled Exposure (1–5 Stops)

The NiSi ND-Vario 1-5 Stops True Color 55mm is a variable neutral density filter that gives you stepless exposure control from 1 to 5 EV. It uses True Color technology to avoid the color shift often seen in other variable filters. You can change density smoothly by rotating the front ring, and the filter is made from high-definition optical glass for clear resolution and image quality.

Key features and how the ND-Vario works

Turn the filter to adjust the density continuously. The density (ND factor) is stepless and controlled by the front filter ring. You can use the included silver lever to aid rotation or remove it if you prefer direct control. The filter has built-in hard stops at each end, so you always know the end positions during action or fast adjustments.

Precise control for photography and video

For photography and video, this filter helps you reduce shutter speed or open aperture while keeping the desired exposure. For video and cinema use, combining aperture and this filter lets you fine-tune depth of field without changing frame rate. The front ring shows visual numbers for stop values, so you can repeat density settings easily.

Design, coatings and handling

NiSi uses an advanced nano coating that repels water, grease and dirt, making the filter easier to clean. The ring is thin to reduce the risk of vignetting on wide-angle lenses, and the front thread is larger to further avoid vignetting on wider lenses. The filter ring is made from high-quality aluminum for a light but strong construction. Silver side knurlings on the ring provide a secure grip for installation and removal.

Practical inclusions and recommendations

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

FAQ

Question: Does this filter cause color shifts in images?
Answer: The NiSi ND-Vario uses True Color technology and is designed to avoid the color shift seen in other variable filters.

Question: How do I adjust the density and repeat a setting?
Answer: Rotate the front filter ring to change density. The ring is visually marked with numbers for stop values to help you repeat settings, and you can use the included silver lever for easier rotation. The lever is removable if you prefer direct control.

Question: Will this filter create the “X” effect at higher densities?
Answer: NiSi lists this product as having no “X” effect.

Question: Is the filter suitable for wide-angle lenses without vignetting?
Answer: The filter has a thin ring and a larger front thread to reduce the risk of vignetting on wider lenses. However, the manufacturer recommends using a variable ND on focal lengths of 35 mm or more (full frame) for best results.

Question: What does the nano coating provide?
Answer: The nano coating repels water, grease and dirt, and it is anti-reflective, which makes the filter easier to clean and helps preserve image quality.
