The difference with the previous HOYA Variable Density filter is the newly designed rotatable frame with convenient knob, allowing for better operation.
Rotatable frame with convenient knob
Variable density filters are widely used because they can replace a set of solid ND filters
Variable density filters lower the shutter speed according to the photographer s intentions
Variable density filters can also increase the amount of boke when shooting
In video shooting, it is fundamental to keep the shutter speed fitting the frame rate setting
By using variable density filters, the shutter speed can be adjusted to the proper value to get that natural and smooth looking motion requested
Due to the specific structure of the filter frame HOYA Variable Density II can take one size bigger lens cap
FOR WIDER APERTURES
PREVENTING OVEREXPOSURE
* When using the filter near or at maximum density a cross-like dark pattern will appear across the image and cannot be eliminated. This is a property of the variable ND filters.
Since HOYA Variable Density II incorporates complex rotatable frame construction, please mind the risk of vignetting as follows:
APS-C size wide angle lenses at focal length less than 13mm
Full Frame wide angle lenses at focal length less than 24mm
LENS CAP COMPATIBILITY
Due to the specific structure of the filter frame HOYA Variable Density II requires a one size bigger lens cap than the size of the filter itself. For example, 77mm HOYA Variable Density II can take 82mm lens cap, as shown on the image below.
