Kase Armour filter holder – fully magnetic for speedy setup

November 15, 2021

Filter maker Kase has announced a new 100mm holder system in which everything fits together magnetically, promising rapid setup. It’s being offered as an alternative to the firm’s excellent, but more conventionally designed Kase Wolverine K9 filter holder. The system is designed to work with full-frame lenses as wide as 14mm without vignetting.

The holder accepts a rear-mounted 95mm polariser and more unusually, 95mm circular neutral density (ND) filters in front. Kase says this allows a lighter overall weight and a completely light-tight design.

This diagram reveals how all of the components of the Kase Armour system fit together. Aside from the lens rings that screw in as usual, everything else fixes together using magnets

In addition, two rectangular filters, either 150x100mm or 100x100mm, can be added using magnetic metal frames which are designed to accommodate conventional 2mm-thick glass filters. These frames also promise increased protection for the glass against drops and handling marks.
