Offering the versatility to fine-tune exposure reduction between 1 and 8.5 stops, the 67mm Variable Neutral Density Filter Kit from Syrp contains an ND filter along with two step-up rings to further extend its use on lenses of varying diameters. The 0.3-2.55 density can easily be controlled by rotating the front filter ring, allowing you to slow your shutter speed or work with a wider aperture setting than normally required. By offering the ability to adjust different density values, this filter can effectively be used in a wide range of situations and controlled to meet your exposure needs.
The optical glass substrate is set within an aluminum alloy filter ring, which features knurled edges for enhanced grip when manipulating the density value or when installing or removing the filter. Additionally, the ring is visually demarcated with index points for repeatable control when adjusting settings. The glass construction is also coated in order to minimize surface reflections and provide greater image contrast and clarity.
Additionally, also included in this kit are two step up rings-58-67mm and 52-67mm-to further extend the versatility of this filter. Both of these step-up rings enable the attachment of this 67mm filter to lenses of smaller diameters.
