Introduction

* Fader ND filter is able to adjust neutral density freely from ND2 to ND400 and carry ONLY a single filter with the same capability with ND2, ND4, ND8 ND16 ND32... and ND400 Rotating it in order to change 1-18 stops. It offers you the freedom the create different neutral density freely.
* The filter is indexed so you know exactly how many stops of neutral density you are getting. It screws on like any other filter and with a mere twist of your wrist, you dial in your filtration. No need to constantly change filters - as the light changes, just dial in another grade of filtration.
* Apply slow shutter speed under strong sunlight exposure.
* Large aperture is available to create depth of field easily.

NOTE:
When using particularly wide angles, a dark cross may appear on your images especially when used on full-frame cameras. This cross may begin to appear at densities of less than 9 stops. The point at which the cross begins to be observed depends on the exact camera & lens combination, but below is a guide of the recommended range of stops which should be sought at varying focal lengths. Used within these ranges, you should achieve even exposure across the image:
12mm: 2 stop (ND4) to 3 stop (ND8) operating range.
15mm: 2 stop (ND4) to 4 stop (ND16) operating range.
18mm: 2 stop (ND4) to 5 stop (ND32) operating range.
24mm: 2 stop (ND4) to 6 stop (ND64) operating range.
35mm: 2 stop (ND4) to 7 stop (ND125) operating range.
40mm: 2 stop (ND4) to 7.5 stop (ND175) operating range.
50mm: 2 stop (ND4) to 8 stop (ND250) operating range
70mm: 2 stop (ND4) to 8.5 stop (ND350) operating range.
