Japanese filter maker Marumi presents its latest range of filters, the Marumi Exus Solid Lens Protect Filter. This new range improves on the company’s existing range of protect filters.

The hardened glass used in a Marumi Exus Solid Lens Protect Filter is now claimed to be up to seven times stronger than conventional lens filters.

We immediately think let us test that theory - it is an ideal opportunity to have a little fun demonstrating the strength of the filter glass while breaking stuff. This task has gleefully been taken up by Marumi, shown in the video here.

The studio scene is set, with a new Exus filter able to withstand a steel ball over 100g in weight being dropped on it from over a metre. Of course a simultaneous split screen shows a conventional filter being smashed to pieces.

If you are the sort of person concerned about protecting your expensive lens, the Exus range should appeal. So far so good.

But what about the image quality with an Exus filter attached? We are keen to see. In the meantime, Marumi reassures us that an Exus filter has an ultra-low reflection rate of 0.2%.

The glass is water and oil repellant, features an anti-static coating and can be cleaned easily from dust and fingerprints.

An Exus filter’s retaining ring that holds the toughened glass features an internal black satin finish, knurled frame and a slim profile in order to avoid vignetting.

We hope to try out these filters shortly, where of course our main priority is to check the image quality. Honestly!
