ND2-400 Name: ultra thin optical mirror 2-400 Frame: ultra thin frame Frame thickness: 1.40 mm Lens height: 7.00 mm Lens material: imported optical glass Frame material: aviation aluminum Lens pressure spring: seamless pressure type Cal. 37mm/40.5mm/43mm/ 46mm/49mm/52mm/55mm/ 58mm/62mm/67mm/72mm/77mm/82mm Commodity characteristics: Adjustable ND2~ND400 ND light mirror When low shutter speed is required (dynamic or continuous images that require long exposure during the day) Need to control sensitivity (ND2-ND400 light-reducing mirrors can maintain the required exposure in very bright outdoor environments) Avoid overexposure of the camera (use this lens to avoid the minimum aperture or exposure) When you need to light up the depth of the scene (in a large aperture, highlight the effect of the subject through a fuzzy background) Commodity description: The outer ring is marked with the "Min" (the brightest) and "Max" (the darkest), the adjustment range of the ND mirror, with ND positioning points among them to help set the level of light loss accurately. If in the ultra-wide angle range+large aperture, adjust to Max with a "ten-word spot," just turn the filter back slightly (towards Min). For example, while filming water in the field, we want to use a 1-second shutter to give the water a soft, cottony texture. However, the shutter speed is still around 1/30 seconds due to the intensity of the light, i.e., the minimum aperture and the minimum iso shot of the camera. The only way to do this is to use one or two ND8 lenses to reduce the light entering the lens. Extrapolation formula: When ND mirror is not installled, the shutter speed of normal exposure is "T" "X" Is the number indicated behind the ND lens, ND4 words x = 4, ND8 words x = 8 When fitted with nd mirror, at the same light, aperture, iso, the normal exposure shutter speed is txx
