Highlights:Variable Neutral Density filters, and ND filters in general have these main uses:
The HOYA Variable Density filter uses high-quality optical glass from Hoya Corporation, the worlds largest optical glass manufacturer and is available in sizes 52mm to 82mm. For best results HOYA recommends using a tripod when photographing with slow shutter speeds. Notes: |
HOYA Variable Density II is a density adjustable filter with an ND range from 1.5 to 9 f-stops (ND3-400).
The difference with the previous HOYA Variable Density filter is the newly designed rotatable frame with convenient knob, allowing for better operation.
