I am a Kase Filters UK champion, I use the AGC circular filter system from Kase filters for all my outdoors and adventure photography. These circular filters are useful in the outdoors as they are small, lightweight and convenient to use in comparison against square filters for mountain photography. I can store the filters with my camera inside the camera insert and not worry about extra filter bags. They are also considerably cheaper versus square filters.
I am a reseller of Kase Filters so if you are interested in buying some Kase Filters please contact me. My store will be available to purchase direct from the website soon.
