These filters fit and work very well, very good quality. I've seen a cheaper plastic set but was concerned about their quality (seemed too cheap) so I went with the mid-range ones. You've got what you need, unless you're a true pro and see the world differently than the rest of us. The Only Negative One of their aspects is a tiny mark on the side for the filter type. They are 4 or 5 pt (contract size :) I marked the handy holder with a pen to make it easier for me. I see no need for anything other than what is included in this pack.
