Kase Armour Magnetic Filter System Review

by Gerard Blacklock

Introduction

I have been using the Kase K9 filter system for a few years now which has been an excellent system with high quality filters, you can read my initial thoughts on this system here. During 2021 the Kase Armour kit was released and in early 2022 I decided to upgrade to this filter system and give it a go. I have been using the Armour kit for over 4 months now and these are my thoughts on the system. All the sample images are taken from the Kase system using a variety of the Kase filters, there are also some product shots, these are taken recently so forgive the dings, dust and scratches on them 🙂 and there is also a short video (located in the summary and also here) showing how the system works, sometimes video is worth a thousand words.

The Kase Magnetic Armour filter system is an evolved unique lens filter system that takes a different approach in the way filters are affixed to the camera lens. Filter systems have developed over the years however the concept of how the filters are attached and used has been pretty much stagnant.
