The Meike ND64 drop-in filter is a professional camera lens accessory designed for precise light control in photography and videography applications. This neutral density filter provides a consistent 6-stop light reduction, equivalent to ND64 density, allowing photographers to achieve creative exposure effects even in bright lighting conditions. The drop-in filter design ensures secure mounting within compatible lens filter holders, maintaining optical alignment and minimizing vignetting. Constructed with multi-coated optical glass, this filter delivers excellent light transmission while effectively reducing reflections and minimizing color cast. The standard neutral density characteristic preserves natural color balance across the visible spectrum, making it suitable for various photographic styles including landscape, portrait, and long exposure photography. The filter features a slim profile design that helps prevent mechanical interference with lens elements while maintaining optical performance. With dimensions optimized for professional filter systems, this accessory integrates seamlessly into existing photographic workflows. The neutral density properties enable extended exposure times for motion blur effects in waterfalls, clouds, or moving subjects, while also permitting wider aperture settings in bright conditions for selective focus techniques. The filter construction includes precision-ground glass elements with edge-sealing to protect against moisture and dust ingress. Compatible with professional camera systems that support drop-in filter configurations, this accessory represents a practical solution for photographers requiring consistent light attenuation without compromising image quality. The ND64 density specification provides reliable performance across diverse shooting scenarios, from bright daylight conditions to controlled studio environments.
