Great filter set with 9 colours to choose from so I can highlight exactly what I want and get more vibrant colours in my photos without editing software. I absolutely love that they are stack-able, for example if you were taking a photo of a Caribbean sunset over the ocean you could accentuate both the water with a blue filter and the sky with a red, orange or purple. You can also blend colours to get different shades. The filters thread together & onto my camera lens very smoothly. I am using it with a Canon lens & Canon EOS camera. My set is the 67mm but I love that I can also use my step up adapter rings to use it with other size rings too. The filters rotate so that you can orientate them where you want. It is a great way to make more intense colours & bring creativity and beauty into your photos. This set comes with a soft microfiber cleaning cloth and it has a nice case with 6 pouches and a case with 3. They are black, have padding to protect the lenses and have nylon mesh pockets to keep the lenses from falling out. The cases have a Velcro closure. It is great to have this many graduated colour filters to choose from and for an amateur photographer or hobbyist it is still affordable. The set is well made and durable. I unintentionally tested the durability of the lenses when I dropped one onto a ceramic floor & it survived without a mark on it. I was provided a sample for quality testing and review. Overall this is a great set of colour filters that won't break the bank. They work great & are fun to work with. What I really need is a vacation or at the very least some nice weather to go out and get some really nice photos. Spring is around the corner I can't wait to get some greenery, sunsets & other great shots.
