I made this 114mm filter adapter to use my Sigma EF 18-35 with the 4x4 square filter holder or compact Mini Mattebox from here:

I’ve precisely modelled the bayonet from the sunhood. You can easily clip-on the square filter holder or the mini matte box to this adapter. There is also additional space in the adapter so you can combine it with round screw in filters like Pro Mist, VNDs, etc.
