Using this ring to allows me to use one set of filters on my two primary lenses. Well constructed, metal ring is threaded both sides, male 52mm for attaching to lens, and 58mm female for filters or other attachments. Threads are very fine and I found that I needed to carefully thread onto and off of my lens several times at first in order to "break it in". It now threads easily. Bear in mind, all lens, filter, etc. threads are extremely fine and easily crossed, TLC required. I don't know why these vendors insist on using camera brands in their descriptions as this type of item is strictly dependent on lens dimensions, but I would recommend to anyone looking to expand the use of their attachments between lenses.
