This PolarPro Helix Variable ND Filter 2-5 Stopfrom PolarPro Helix Variable ND Filter 2-5 Stopis designed for the Helix magnetic filter system and provides an exposure reduction of 2 to 5 stops. It darkens the entire image area, allowing a wider aperture or slower shutter speed than is usually possible. Increasing neutral density offers finer control in available shutter speeds or aperture settings for both still and video applications. Using a longer shutter speed makes it possible to increase blur to convey a sense of movement or to dial in a video camera frame rate. Increased density also makes it possible to shoot using wider lens apertures, helping to isolate a subject from the background and increasing bokeh. This filter provides 2-, 3-, 4-, and 5-stop density increase. The front ring features a numbered scale of the stop values, and it also features haptic feedback to feel a click when reaching a number without looking at the ring. The ring features side knurling for a secure grip and to further enable fast and precise positioning.

Unlike other magnetic filter systems, the Helix system provides a completely secure connection using a magnetic connection plus a quarter-turn locking mechanism, making it lightning-fast to install and remove filters. This advanced locking system ensures filters stay locked in position, even during the most demanding shooting situations.

Q: 6. I have a h&y 67mm-82mm Revo ring that measures 11cm in outerdiameter, would this fit?

A: If the outer diameter of your lens is 11 cm (which would be 110 mm), we cannot guarantee the PolarPro 114mm Defender Lens Cover would fit on your lens as it is designed for lenses that are 114mm in diameter. However, as it does have a bit of elasticity, it may be able to work for your usage needs. I would recommend as the above item may be returned within 30 days of the delivery date for a refund or exchange, you can purchase the item to check and see if it works on your equipment, and if not, you may return the item.
