Digital Camera World Verdict

The Kase Armour filter holder is slim but robustly made and it attaches securely to the magnetic lens adapter. The high-quality filters also mount securely and are easy to adjust, but the filter frames seem a little on the pricy side.

Why you can trust Digital Camera World Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out how we test.

Kase produces a range of filters with different mounting options from the traditional slot-in type of the Wolverine K9 series to magnetic circular filters. The Armour system is compatible with the company’s existing 100mm type filters that can also be used in the K9 holder, but they must first be mounted in a magnetic filter frame. It also accepts 95mm Armour circular filters, but it’s not compatible with the company’s existing/other circular filters.
