The attachment does not accept screw-in filters directly, they would vignette due to the very wide angle of view. The outer diameter of the Century .6x is 95mm. You need a Matt Box / Sunshade that will fit a 95mm accessory that uses 4x4 filters and has a design that will not vignette with the attachment. Chrozeil, Century, Vocas, and Birns and Sawyer all offer them but be sure whom ever you talk to knows that it is the Century .6x on the DVX 100.
I do not know about the compatibility of Cavision or Formatt.
You might be able to use a 95mm to 4 1/2" or 138mm adapter and use 4 1/2" or 138mm round filters but in the long run you need a shade/matte box for 4x4's so spending several hundred dollars on large round filters and adapters would seem unwise--- even if it works.
