This set of filters was delivered fast and well-packaged. It consists of a set of three lens filters: UV, circular polarizing and a variable Neutral Density 2-400 which is 9 f-stops of adjustability.

A UV filter, of course, is just glass, which blocks UV. And circular polarizer or CPL filters reduce glare and increase color saturation by reducing washout from reflections. If you have polarizing sunglasses you know how useful that can be. But as you may know, sometimes when you are wearing such sunglasses and you look at certain things, like your camera or phone LCD screen, it makes it very dark or even completely black. That’s because such screens incorporate polarizing technology and two such polarizers arranged at right angles cancel each other out. So guess what? Variable ND filters are just two polarizers stacked so that when you rotate one on the other progressively more light is blocked out just like using your (usually vertically) polarized sunglasses to look at (horizontally) polarized LCD screens. Pretty clever!

All that said, these filters are an essential tool for anyone serious about photography. This set, in other words, is indispensable. They are excellent quality as well from a manufacturer known for good quality at affordable prices. Yes, you can get better for more money as with anything. Chiefly, you can get more expensive glass and coatings. But to get all three of these filters together, along with a nice carry case that protects all three for $33.49 – list as of this writing – is a tremendous deal. Get these, use them in different circumstances and see how you like the results. You can always get more expensive ones later.

One more thing: unlike some other products, especially clip-on filters for cellphones, you can stack these. That is, you can keep the UV filter on your lens and add the CPL as needed. Or, what may make more sense – what I usually do – is keep the CPL filter on most all the time and add the ND filter when needed.
