Enhance Your Photography with Our Variable ND2-400 Lens Filter Variable ND Filter: Experience unparalleled control over your shots with our adjustable neutral density filter. Designed with a combination frame, this filter allows you to rotate the lens smoothly, transitioning seamlessly from light to dark. By turning the frame, you can achieve a variable ND value effect, offering precise exposure control that adapts to various lighting conditions. Wide Compatibility: Our adjustable ND filter employs the innovative principle of stacking two CPL filters, providing a versatile range of ND values from ND2 to ND400. This range is perfect for most photography needs, though higher density ranges like ND1000 and ND2000 are not supported, ensuring optimal performance within its designed spectrum. ND2-ND400 Filter: Simply attach the filter to your camera lens and point it at bright areas such as the sky. Rotate the filter from minimum to maximum settings while observing the color changes through your viewfinder. If you notice uneven light reduction, note the corresponding scale position as a guide for long exposure adjustments. Longer exposures are generally needed to eliminate X shadows, particularly in high-density ranges, ensuring balanced, high-quality images. Usage Instructions: Uneven light reduction is not a defect but results from Moore fringe. To eliminate the X shadow, extend your exposure time sufficiently. The filter's maximum position is its limit; as you approach ND1000, usability decreases significantly. For best results, the recommended effective range for this filter is ND2-400. Long Lasting: Constructed from shock-resistant tempered optical glass and encased in a durable aluminum alloy frame, this variable ND lens filter is both lightweight and robust. Its design ensures longevity and resilience, making it an almost unbreakable addition to your photography toolkit, ready to withstand the demands of professional use.
