ZOMEI 67mm ND2-ND400 Variable ND Filter

Introduction: By rotating the end of the lens, you can control the amount of light entering the lens, ranging from +1 to +8 stop values. For example, you can use f/4 instead of f/8 for selective sharpness or 1/15s instead of 1/60s for a smooth, blurred water effect.

Color Shift: The color of the image may vary between warm and cold when using variable ND filters. Adjust your white balance accordingly when setting the ND filter to different ranges.

Lens Cap or Lens Hood Compatibility: The outside thread of the filter is larger than the inside thread, a special design to reduce the possibility of vignetting at wide angles. If you want to use a lens cap, you may need to remove the filter or use a larger thread cap.

What's In the Box: One 67mm Slim ND2-400 filter.

How Does a Variable ND Filter Work? Instead of carrying multiple ND filters with different densities, a variable ND filter allows for flexible control of light by using two polarizing filters, one of which can rotate. As the filters are rotated, the amount of light reaching the sensor can be adjusted with almost infinite control.

Features Of the Zomei Variable ND Filter: The Zomei Variable ND Filter 2-8 stops uses two polarizing layers to control the light passing through the filter. It allows for 1/3 to 1/400 of light to pass through, creating artistic blurring effects. High-quality optical glass is used, and the filter is available in various thread sizes.

Why Is There a "X" Cross Pattern (Vignetting) in Images? The "X" cross pattern can occur with wide angle lenses and variable ND filters when used beyond their capabilities. The physics of optical filters may cause this issue when pushed to their limits.

Additional Features of the Zomei Variable ND Filter: - Allows for the use of slow shutter speeds - Provides control over depth of field - Enables shooting high-speed film in bright outdoor situations

Examples of Neutral Density Use: - Blurring water motion - Reducing depth of field in bright light - Adding motion blur to subjects - Extended time exposures

Creating Smooth Waterfalls, Rivers, Oceans: By using the ND filter to limit light, photographers can adjust shutter speed for desired motion effects without sacrificing aperture settings. This allows for creative control over capturing subjects in motion such as waterfalls, rivers, and oceans.

Overall, the Zomei Variable ND Filter offers a thin, anti-reflective coating, variable light reduction between 2-8 stops, protection against dust and scratches, and compatibility with slow shutter speeds. The filter also helps decrease depth of field and prevents vignetting at wide angles.
