Hoya 77mm Variable Density II Filter

What sets the HOYA Variable Density II Filter apart is its adjustable density feature, offering an ND range from 1.5 to 9 f-stops (ND3-400). This upgraded version from the previous HOYA Variable Density filter boasts a newly designed rotatable frame with a convenient knob, enhancing user operation.

Variable density filters, like the HOYA Variable Density II, are essential tools for photographers and videographers. They offer the flexibility of a range of densities that can be adjusted to match the desired exposure settings, effectively replacing a set of solid ND filters.

In still photography, these filters allow photographers to control the shutter speed based on their creative vision, especially when camera limitations prevent a lower shutter speed. They also increase the bokeh effect in over-lit conditions, preventing image overexposure.

In video shooting, maintaining the right shutter speed to match the frame rate setting is crucial. The HOYA Variable Density II Filter helps achieve this balance, preventing a jarring effect and the production of undesirable afterimages. By adjusting the shutter speed with the variable density filter, videographers can capture natural and smooth motion in their footage.

The HOYA Variable Density II Filter features an exclusive rotatable frame construction, consisting of a fixed frame and a rotatable frame. The rotatable frame is designed wider than the fixed frame to minimize the risk of vignetting when used on wide-angle lenses. However, users should be aware of potential vignetting with APS-C size wide-angle lenses at a focal length less than 13mm and Full Frame wide-angle lenses at a focal length less than 24mm.

Due to its unique filter frame structure, the HOYA Variable Density II can accommodate a lens cap one size larger than the filter itself. For instance, a 77mm HOYA Variable Density II can take an 82mm lens cap.

The HOYA Variable Density II Filter provides the freedom to change the shutter speed for longer exposures without altering the aperture. This is particularly effective for motion blurring effects, such as capturing waterfalls, moving cars, or creating a blurred panning movement to make the subject stand out from the background.

In over-lit conditions, the filter allows for wider apertures to decrease depth-of-field, focusing more attention on the subject. It also prevents overexposure, even with a shutter speed of 1/8000 seconds and a large aperture of f/1.4 or f/1.2, by adjusting the light intake.

For video bloggers and professional video content creators, the HOYA Variable Density II Filter is a must-have. It allows cine/video cameras to set the appropriate exposures in bright lighting conditions to achieve a cinematic look.
