NiSi IR ND filters use exclusive dual-sided Nano coating technology. They features ultra low color shifting with anti-reflective coating, optimized for shooting 6K or above 6K RAW digital images.

The bundles includes two types: Professional bundle as six pieces of glass, and Core bundle as three pieces of glass. It saves a lot compared to single piece.

Description

NiSi IR ND uses H-K9L high quality optical glass, with double-sided nano-coating, to reduce the intensity of visible light entering the lens, It will not change the brightness contrast of the scene, and also provides effective inhibition of ultraviolet and infrared light. The Nano Coating technology of NiSi IR ND has been innovated by NiSi Filters. Please visit NiSi IRND page to get more tech information.

Kinefinity provides two practical bundles:

  1. Core Bundle (Three pieces): 0.3/0.6/1.2. You can also choose any three pieces of glass including different f-stops even polarizer, the same size;
  2. Professional Bundle (Six pieces): 0.3/0.6/0.9/1.2/1.5/1.8. You can also choose any six pieces of glass including different f-stops even polarizer, the same size.

Please make note for the type of your ND if what you choose is not default.

电影滤镜说明

滤镜根据遮光斗大小分为三种常见尺寸:

  1. 4×4″:外置电影滤镜中最小的尺寸;适合于不超过100mm口径的镜头;
  2. 4×5.65″:是最常用的电影滤镜尺寸;适合于不超过100mm口径的镜头;
  3. 6×6″:适合于19毫米系统,超过110mm口径的电影头,需要6×6″的滤镜才能覆盖。

此外,外置的电影滤镜需要安装在遮光斗的滤镜架上。一个滤镜架只能安装/固定一片4mm的滤镜。而一般遮光斗可以同时安装两个滤镜架,实现两个滤镜叠加的效果。滤镜架也分为上述三种尺寸。所以购买滤镜或者遮光斗时需要确认好彼此的尺寸,避免无法安装。

此外,电影中灰镜/IRND一般用数字标识:该数字直接对应于减弱的档位。0.3表示一个档位/f-stops:

  1. 0.3表示降低1档;
  2. 0.6表示降低2档;
  3. 0.9表示降低3档;
  4. 1.2表示降低4档;
  5. 1.5表示降低5档;
  6. 1.8表示降低6档;
  7. 2.1表示降低7档。

中灰镜还可以直接叠加以增加档位。比如0.3和0.9叠加会得到1.2的中灰镜效果,相当于4档的减弱了。
