Nice little filter kit for 55mm lens. . I like to have at least a UV filter on all of my lenses to protect the glass and keep it clean. It has a UV filter that I always leave on my lens, a circular polarizer (CPL) Neutral density (ND2) filter, fluorescent light for daytime (FL-D), cleaning pen, cleaning cloth, Petal hood, spring loaded lens cap & lens cap keeper. The filters feel like glass to me some of the cheaper sets are not made of glass. The lenses have threads so they are stackable which means if you want to leave your UV on for example and use your CPL you can thread it in on top. The filters come in a padded storage case that is black & orange, have a Velcro closure and 4 mesh pockets. The cleaning pen has 2 sides, a retractable brush on one end and a felt lens cleaner on the other end with a cap. It works great for cleaning lens, filters and camera equipment. The petal hood threads in securely, helps protect the lens & reduce flare, it doesn't show up in a shot. The lens cap clips right into a 55mm lens, a filter or the hood.UV filter mostly protects expensive camera lens & subtly reduces UV & haze tooCPL Circular polarizer- Reduces reflection, improves contrast & colour saturation. It also adds drama to your photo best when you are 90 to the light source. Changes effects when rotated.ND2 Neutral Density 2 Slows shutter speed by 2 stops to reduce aperture, makes running water look smoother & you can get a longer exposure to give different artistic effectsFL-D For fluorescent lighting in daylight corrects the white balance in fluorescent light & can make colour more natural.If you have any questions I would be happy to try and answer them for you. I am not a professional photographer by any means but I like to learn about my gear so I can get the most out of my investment. I was given a discount or sample for quality testing and review. Overall this is a great starter kit, it is a good value and has a lot of nice extras in it. Nice variety & I'm happy with it.
