The 4-stop, 4 x 5.65" Tiffen Hard-Edge Graduated ND Filter 4x5.65" 4-Stopis a graduated neutral density filter that helps to specifically darken skies and other bright areas of the image. The filter is densest at the edge and tapers to clear by the middle, with a hard-edged line of transition between the density and clear areas. Neutral density filters do not affect the coloration of the image and the 1.2 density provides a 4 stop reduction in light from entering the lens.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 5.65" / 101.6 x 143.5mm.

Note: A vertical orientation filter's line of transition runs parallel to the short side of the filter.

Q: 9. IT SAY'S IT CAN "power your gear for up to 8.25 hours" BUT WHEN I GO TO THE Q&A IT SAYS 2-3!?

A: The Core SWX Powerbase EDGE Battery on its own, can power other devices besides the suggested camera for this package (Blackmagic Design Pocket Cinema Camera 4K / 6K). The manufacturer, Core SWX states that it can power for up to 8.25 hours on "a small DSLR/mirrorless camera", which could also be power by this setup. For a Blackmagic Pocket Cinema Camera 4K / 6K the power demands are higher and you would get less time.
