Works well


from Athens, GA.  -  Photo Enthusiast

I've always been amazed that something as inexpensive as close up filters work as well as they do (other photography extras tend to cost, you know)and a "used" filter that you sold me to fit my new Nikon works as well and looks as new as the ones I bought years ago for my little Pentax. Whoever "used" it must have used it just once, it even had the original case it came in, in mint condition. Thanks.
