These things are awesome! I have noticed these make a beneficial impact to my photography in the year I've been using these. They screw on easily, and they stay there. The CPL has a collar around it and acts as a bearing for my lens hood. That works perfectly.The FLD works-if you have a full spectrum CFL lamp or set of lamps like that. If they're not full spectrum, it's not of use. However, if you need to get rid of the green cast from a light with mercury vapor in it, it will do that perfectly.If you use all three of these in a stack, you are likely to get some vignetting. It edits out, but if that's an issue, keep it in mind and try to work your shooting around that. It's not major, but it's there. I generally use the CPL and UV filter in tandem. With those two alone, I don't recall having a whole lot if any vignetting most of the time. Others have commented on this-but I have yet to experience that with 1 or 2 of these in a stack.The lenses are plastic, but they work. The frames are metal. I have yet to have an issue with these in the year I've been using them. The only issue I have run into is nothing that a lint free cloth won't fix. :)
