This is a wide-conversion lens from Sony. I purchased it, but I am selling it because I no longer have a use for it. I bought it as a used item in good condition, but I only used it once. When attached, it provides a 0.7x wide-angle effect. The lens has 52mm threads. There are no noticeable scratches or dirt on the lens, but please check the condition in the photos. The accessories are everything shown in the photos. I am selling it as a used item, a junk item, because I no longer use it. Please understand the above, and no claims or returns are accepted.
