I have a Nikon DSLR kit for beginners as well as a more advanced kit and each came with two lenses. I am still learning how to use the advanced camera, but I feel fairly proficient with the beginner's model and I'm interesting in trying out new accessories. I needed protective lens filters for all of the lenses, and I have been slowly building up a collection of filters with various effects and learning what each of them can do. I like to take portraits so I was intrigued by the softening effects possible with this 1/4 black diffusion mist filter. I ordered the 55 mm version to use on a 70 -300 mm Nikkor zoom lens and it fits perfectly. It is very thin and light and I can use it with other filters as I gain a little more experience. So far, I have only used it by itself to take pictures of our dogs and some interesting plants and flowers. It really does blur background lights and helps to reduce contrast on the subject and refine the image. The glass and coatings are of excellent quality and clarity and the current price of of $49.99 for this lens filter seems very reasonable. It comes with a cap as well as a simple case for storage.
