This is a very well made diffusion filter and the glass and coatings are of excellent quality. I ordered a set of K&F diffusion filters for one of my lenses that is part of a camera kit that I received as a gift (my "fancy" camera that I am still learning about). I'm still fairly new to DSLRs in general and lens filters in particular, but now that I have seen some of the effects I can get with some of the filters I have purchased for this kit, I have been working on building up a nice collection for all of my cameras. I have several UV and ND filters from this brand and they seem every bit as good as the older name brand lenses I purchased for my film cameras years ago (for a photography class I was taking at the time). So I didn't hesitate to order this filter for one of the lenses in my more basic camera kit, the one that I use with more confidence. I like to take close-up pictures of flowers, leaves and insects as well as of my pets and I really like how this filter softens edges and seems to emphasize contour and color. I chose the 52 mm lens and it is very thin and light and threads on to my lens easily. The filter arrived carefully packaged like everything from this brand and included a sturdy hinged protective case. I think the price is great for a lens filter of this quality.
