This PolarPro Summit Landscape Filter Holder Kit is designed to allow for the convenient use of up to two neutral density filters along with a circular polarizer filter on lenses with 77 or 82mm front filter threads. Included is a PolarPro Summit Core Filter Holder, a PolarPro Summit Neutral Density 1.8 Filter, a PolarPro Summit Soft-Edge Graduated Neutral Density 0.9 Filter, and a PolarPro Summit Circular Polarizer Filter. The two neutral density filters are each encased within a durable and lightweight filter frame. By encasing the sides of a filter, the filter frames help to eliminate or limit stray light, which could have unwanted effects on exposure, from coming in between a filter placed within the filter holder, as well as the filter holder and the lens behind it. Additionally, the filter frames reinforce rigidity of the neutral density filters while preventing their sides from having to come into direct contact with the filter holder's slots. This protects those side surfaces and promotes sharp results by ensuring that the filter remains flat. The PolarPro Summit Core Filter Holder includes a dedicated inner slot for PolarPro Summit neutral density filters that feature quick-access side handles. The combination of that slot and the side handle allows a PolarPro Summit neutral density filter within a PolarPro Summit Core Filter Holder to be quickly switched with a different PolarPro Summit neutral density filter needed for other subjects or changing lighting conditions. An outer slot on the PolarPro Summit Core Filter Holder can accommodate a PolarPro Summit graduated neutral density filter that also includes a side handle. The filter holder also features locking knobs that are each dedicated to one of those slots, allowing a PolarPro filter within a PolarPro Summit Core Filter Holder's corresponding slot to be secured, while an installed PolarPro Summit graduated neutral density filter can be adjusted upward or downward relative to the subject. Use of the filter holder can be easily accomplished by first screwing one of two included adapter rings onto a lens with 77 or 82mm front filter threads. After being fitted onto the adapter ring, the filter holder's main locking knob helps to provide a reliable, yet adjustable connection that allows the holder to be rotated 360°, further benefiting the use of graduated neutral density and other filters that are enhanced by varied positioning. Additionally, adapter rings are separately available for lenses with 67, 72, or 95mm front filter threads. The PolarPro Summit Core Filter Holder also accommodates an included drop-in circular polarizer filter. An external dial on each side of the filter holder integrates with the polarizer's filter ring, allowing for the independent rotation of the circular polarizer filter to adjust the intensity of its effect. Utilizing aluminum alloy components, the PolarPro Summit Core Filter Holder is durable while remaining lightweight. A snap-on filter holder hood is included to further block unwanted stray light, as is a padded case that can fit the entire PolarPro Summit Landscape Filter Holder Kit during storage and transport.
