Thank you for viewing. This is a Kenko lens filter, Softon A. Filter diameter: 77mm *The effect is subtle, creating a slightly soft overall look, so you might consider leaving it on all the time. I'm selling this to organize my filters. (For some reason, I had two of the same one... lol) I bought this quite a while ago, but I haven't used it very often, so I think the filter itself is in relatively good condition. There's no damage that would affect the images, but it's a used item, so please refrain from purchasing if you are overly concerned about its condition. Please check the attached images for the condition. Thank you for your consideration.
