NiSi ND-VARIO 1-5 Stops True Color 49mm Variable ND Filter

NiSi ND-VARIO 1-5 Stops True Color Variable Neutral Density Filter 49mm

The NiSi ND-VARIO 1-5 Stops True Color is a variable neutral density (ND) filter designed to provide precise exposure control by reducing light entering the lens from 1 to 5 stops (EV). The ND factor is continuously adjustable by rotating the filter, allowing stepless control over exposure settings.

Key Features

• Variable ND range from 0.3 to 1.5 density, corresponding to 1 to 5 stops exposure reduction
• True Color technology ensures no color shift or "X" pattern effect common in other variable ND filters
• High-definition optical glass for superior image quality
• Advanced nano coating repels water, grease, and dirt, facilitating easy cleaning
• Thin aluminum filter ring minimizes risk of vignetting on wide-angle lenses
• Front ring marked with stop values for repeatable and precise density adjustments
• Silver side knurling on the ring for secure grip and easy installation/removal
• Built-in hard stops at each end of the rotation range to indicate filter position during use
• Optional removable silver lever for easier rotation and exposure length predetermination
• Larger front thread to avoid vignetting on wider lenses

Usage and Benefits

This filter is highly useful for both photography and videography, allowing the user to adjust the amount of light entering the lens precisely for each scene. This enables the use of larger apertures and/or longer shutter speeds than would otherwise be possible under current lighting conditions. For cinematography and video applications, combined adjustments of aperture and this filter allow fine control over depth of field while maintaining the desired frame rate.

Construction and Compatibility

The filter ring is made from high-quality aluminum, making it lightweight yet durable. The thin profile ensures compatibility with wide-angle lenses without causing vignetting. It is recommended to use this variable ND filter on lenses with a focal length of 35 mm or longer (full-frame equivalent) for optimal results.
