I am very proud to now be apart of the Kase filters team as an official re-seller. The Kase Wolverine filters are fantastic quality and produce some of the most neutral results and alongside the 100mm slim K8 filter holder its a brilliant system for amateurs and pros alike. Here is some images below showing the filters and the holder, And a link to the Kase website where you can buy the filters. I will get a small commission with any purchase made through this link with no extra cost to you. This helps me and my photography massively, and i do appreciate your support.
