HOYA VARIABLE ND FILTER II 77MM

HOYA VARIABLE ND FILTER II 77MM

HOYA Variable Density II is an adjustable density filter with an ND range of 1.5 to 9 f-stops (ND3-400).

The difference with the previous HOYA variable density filter is the newly designed rotating frame with a convenient knob, allowing for better operation.

WHY VARIABLE DENSITY FILTERS ARE IMPORTANT

• Variable density filters are widely used because they can replace a set of solid ND filters by providing a range density that can be adjusted according to the desired exposure settings.

• In still photography, variable density filters reduce the shutter speed according to the photographer's intentions when the shutter speed cannot be reduced due to camera limits.

• Variable density filters can also increase the amount of bokeh when shooting in overlit conditions, thus preventing the image from being overexposed.

• In video recording, it is essential to keep the shutter speed adjusted to the frame rate setting. That is, keeping it equal to double the frame rate for optimal results. This is because, unlike still photography, an excessively fast shutter speed can create a jarring effect and produce images that will not look good in the final video.

• As you can see in the image below, unlike a still image, a video clip is made up of a sequence of still images. With a low shutter speed, each still image will be blurred, but it will look smooth in the video sequence. Conversely, a higher shutter speed will capture the object solid and sharp, but once in a video sequence, all objects will appear separate, creating a jarring and unnatural-looking motion.

• By using variable density filters, the shutter speed can be adjusted to the appropriate value to achieve that natural and smooth-looking motion requested in video images, as shown in the image below.

ADVANTAGES
FOR LONGER EXPOSURES

• Without changing the aperture, the HOYA Variable Density II provides the freedom to change the shutter speed according to the desired effect. Effective for motion blur effects like waterfalls, cars, or blurry panning movement to make the subject stand out from the background.

FOR WIDER APERTURES

• Allows wider apertures to be used in overlit conditions to decrease the depth of field, literally focusing more attention on the subject.

PREVENTION OF OVEREXPOSURE

• Even with a shutter speed of 1/8000 seconds, a large aperture of f/1.4 or f/1.2 can cause overexposure. With the HOYA Variable Density II filter, overexposure problems can be avoided by adjusting the light input.

FOR RECORDING VIDEO WITH A CINEMATIC LOOK

• The variable density filter is a must-have for video bloggers and professional video content creators. It allows film/video cameras to set proper exposures in bright lighting conditions to achieve a cinematic look.
