- Variable ND range ND2-400 with a rotating ring for easy light compensation. Reduces light intake without affecting color balance. - Allows slow shutter speeds on bright scenes with fast-moving subjects to capture motion blur in waterfalls, clouds, or other rapidly moving scenery. Slim edge design prevents wide-angle vignetting, and the robust aerospace aluminum frame provides lasting durability. - 8-layer MRC (multi-resistant coating) protects against water and dust. Extra rugged frame helps ensure longevity and minimizes the risk of jamming. - Reduces depth of field by enabling a wider aperture and helps separate the subject from the background. - Use scenarios: - Long-exposure landscape photography on sunny days to smooth moving water and cloud movement without changing color. - Nighttime or daylight cityscapes where motion blur of flowing elements can be desired while maintaining overall exposure. - Video or time-lapse shoots that require controlled light and reliable performance in challenging conditions.
