This Kase K9 100mm Slim Entry-Level Filter Holder Kit contains a Kase K9 100mm Filter Holder, a Kase 100 x 150mm Wolverine Oversized Slim 1.1mm Thick Solid Neutral Density 1.8 Filter, a Kase 100 x 150mm Wolverine Soft-Edge Graduated ND 0.9 Filter, as well as a Kase 90mm Magnetic Circular Polarizer Filter that is designed to avoid vignetting when used with a wide-angle lens. The neutral density filters can be used individually or in combination to improve the results of your photography by preventing overexposure, along with the circular polarizer, which serves to prevent distracting reflections or glare.

Utilizing a modular filter slot system, the filter holder allows for the convenient use of up to three, 100mm wide, 1.1mm thick filters such as the included Kase Wolverine neutral density filters, along with the included circular polarizer. The slot system can also be reconfigured so that the kit's filter holder accommodates up to three, separately-available 100mm wide, 2mm thick filters along with the circular polarizer filter. While in use, the circular polarizer filter magnetically fits within the filter holder system so that it can be quickly installed, removed, or switched with a different Kase 90mm magnetic filter depending on the subject or changing lighting conditions. Kase slim 1.1mm thick filters are designed to be 43% lighter and 45% thinner than 2mm thick Kase filters. The slim, 1.1mm thick design can help prevent vignetting when used in a compatible filter holder along with one or two other 1.1mm thick filters.

Constructed for durability while remaining lightweight, use of the K9 100mm Slim Entry Level Filter Holder Kit is easily accomplished by first screwing one of its included 77 or 82mm adapter rings onto a lens or step-up ring with corresponding front filter threads. A 67-82mm step-up ring as well as a 72-82mm step-up ring for use with the 82mm adapter ring are also included for lenses with 67mm or 72mm front filter threads, respectively. After being fitted onto an adapter ring, the filter holder's locking knob helps to provide a reliable, yet adjustable connection that allows the holder to be rotated 360°, which benefits the use of graduated neutral density or other filters that are enhanced by varied positioning. The included circular polarizer filter can then be placed within the filter holder assembly, followed by 100mm wide filters that are either 1.1mm or 2mm thick.

The adapter rings accommodate the magnetic circular polarizer within the filter holder system. When combined with both the adapter ring and filter holder, the circular polarizer filter can be rotated to adjust its effect. An external dial on the filter holder integrates with the polarizer's geared filter ring, allowing for the independent rotation of the circular polarizer filter in order to adjust the intensity of the polarization effect. Two pairs of screw-in guide blocks are included. When installed, one guide block pair creates three slots for 100mm wide, 1.1mm thick filters while the other guide block pair creates three slots for 100mm wide, 2mm thick filters.

The Kase 100 x 150mm Wolverine Oversized Slim 1.1mm Thick Solid Neutral Density 1.8 Filter provides a 6-stop exposure reduction. Its 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you can control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters. The Kase 100 x 150mm Wolverine Oversized Slim 1.1mm Thick Solid Neutral Density 1.8 Filter is also 50% longer than a 100 x 100mm solid neutral density filter. Its extra length provides additional handling surface to help prevent fingerprints from accumulating on the section of the filter that would be positioned in front of a lens. As a result, the appearance of fingerprints in an image or recording made with this filter can also be prevented.

The Kase 100 x 150mm Wolverine Slim 1.1mm Thick Soft-Edge Graduated ND 0.9 Filter helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. This filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. A neutral density filter with a soft-edged line of transition is able to filter the sky while minimizing its effect on the land. It is particularly useful where the transition between sky and foreground is indeterminate, such as images featuring mist, fog, or the tops of trees. Neutral density filters do not affect the coloration of the image and this filter provides up to a 3-stop reduction in light from entering a lens.

Kase Wolverine filters are constructed from tempered, optical glass for shock resistance. To prevent internal ghosting and reflections, while further enhancing clarity and color fidelity, each glass surface includes multiple layers of anti-reflection coatings. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.

To store and transport the Kase K9 100mm Slim Entry-Level Filter Holder Kit, a rigid, leatherette pouch is provided. It features a secure, buckle closure as well as a shoulder strap that can be used to keep its contents within immediate reach.
