I have been a user of these filters for the past year and have been absolutely astonished by their colour and build quality, ease of use and clarity. All workshop and 1-2-1 clients have access to a range of Kase filters for demonstration purposes.
The main 100mm kits come in 3 basic set up to take you from entry level use of the Kase filter system right up to Master level. These are detailed below by clicking on the Filter Kits. I have also included some of the key filters that I have found most useful during landscape and seascape photography and some accessories This isn't an exhaustive list of the Kase products though so if there is anything that you would like to order then please contact me.
