MARUMI CREATION VARI.ND (ND2,5-ND500) 67mm
There is the case that you carry multiple standard ND filters and choose one of them, or stack them to realize desired ND value at the shooting site. This filter can reducelight intensity over a wide range from 1/2.5 to 1/500. Since the desired ND value can be adjusted by rotating the filter ring, there is no need to carry many ND filters with different densities. Despite of its double frame structure, it employs slim profile frame (thickness is 5.9mm without thread) to prevent vignetting.

For adjusting exposure time
The desired shutter speed can be adjusted without changing the aperture.
For adjusting aperture
The desired depth of field can be obtained by adjusting aperture without changing the shutter speed.
Effective for creating digital movie
Since the shutter speed is fixed for digital
video camera (ex. 1/60sec., 1/50sec., 1/24sec., etc.), the light volume has to
be controlled to adjust aperture for the desired depth of field. This filter is
effective to obtain it at any values.
This filter is useful for making fade out effect also.
Key Features
· Multi-coating for low reflections
· Satin finished frame
· Knurling on the frame for easy operation
· Blackened outer rim for reducing inner reflections
[REMARK]
In the range of high density, the cross pattern
image may happen depending on shooting condition.
