Nicna 55mm 55 mm Fader ND Filter ND2 to ND400 Wide Angle

Wide-angle Adjustable reduce-light filter(Hereinafter referred to POL filter),
The filter is made of two pieces of high polarizer (HPL) which has above 99.7 polarization and a precision rotary of the wide-angle lens ring. (The filter itself is not the wide-angle lens)
(Note: P-type instrumentation series called "stepless dimmer filter" which is used by PS072 and P049 combo installed in the P-sets of seat)

Through the polarization angle modulation (rotate the filter ring when operating), this lens can change the luminous flux substantially with freedom, reducing the amount of light can from two times of the lowest to about 400 times of the highest (It is ?"3% at maximum density), In this sense, it can be easily replaced by dozens of all grade of density ND gray filters(maximum equal to 3 ND9) (1 ND9 light can be reduced three grade light).The operation is extremely convenience when selecting your desired density, Just rotating filters.

Features:

A, In the Strong light environment, to shoot the scene of small depth of field (Blur the background, thus showing the main body).

B, In a bright environment, using high-density photography to shoot the scene of dynamic objects.

C, When transferred to high-density, to shoot the clarity of the details which is usually difficult to observe by the human eyes (such as steel, welding, solar eclipse, magma, etc.) in the  high temperature and bright environment, 

D, On a sunny day and night shooting simulation (For example: Under the backlighting, the filter has a strong reflection, you can transfer the POL Filter to an appropriate density, and then jump spot density control exposure, access to the charming moonlight atmosphere).

E, In a bright environment to shoot strong dynamic screen (such as streams, waves, athletes, wind and vegetation, etc.), often use a longer shutter time, to blur the whole movement or a part.

F, Modulation to the appropriate density for flash photography at close distance.

G, Used in variety of the scenes which need a wide range of adjustment the amount of light.

H, POL filter also apply to a variety of wide-angle lens
