Utilizing a modular filter slot system, this Kase K9 100mm Filter Holder Kit allows for the convenient use of up to three separately available 100mm wide, 2mm thick filters along with an included Kase 90mm Magnetic Circular Polarizer Filter that is designed to avoid vignetting when used with a wide-angle lens. The slot system can also be reconfigured so that the kit's filter holder accommodates up to three, separately available 100mm wide, 1.1mm thick filters along with the circular polarizer filter. While in use, the circular polarizer filter magnetically fits within the filter holder system so it can be quickly installed, removed, or switched with a different Kase 90mm magnetic filter depending on the subject or changing lighting conditions.
Kase K9 100mm Filter Holder, Adapter Rings, and Step-Up Rings
Durable, lightweight filter holder allows for the convenient use of up to three separately available 100mm wide filters that are either 2mm or 1.1mm thick and an included Kase 90mm Magnetic Circular Polarizer Filter
One pair of included screw-on guide blocks creates three slots for 100mm wide, 2mm thick filters while another pair of included screw-on guide blocks creates three slots for 100mm wide, 1.1mm thick filters
Use of the filter holder can be easily accomplished by first screwing an included 77 or 82mm filter holder adapter ring 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
Filter holder locking knob helps to provide a reliable, yet adjustable connection that allows the filter holder to be rotated 360°, allowing the use of graduated neutral density and other filters that are enhanced by varied positioning
Kase 90mm Magnetic Circular Polarizer Filter
Circular polarizer filter magnetically fits within the filter holder system and can be quickly installed, removed, or switched with a different Kase 90mm magnetic filter depending on the subject or changing lighting conditions
Polarizer filters help to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface, clears up haze in distant landscapes, and provides more saturated, vivid colors
Does not disrupt auto exposure or focus features, is constructed from Schott B270 Superwhite glass for enhanced clarity and color fidelity
Multi-coated to prevent internal ghosting and reflections and features scratch-resistant, mold-resistant, and hydrophobic coatings on each glass surface to protect the filter substrate and result in an improved beading effect when in contact with water or oil for greater cleaning efficiency
2x filter factor reduces exposure by 1 stop
Designed to avoid vignetting when used with a wide-angle lens and can be independently rotated to adjust the intensity of the polarization effect
