Q: 3. It's a little tough to tell in the pictures. Is this ring threaded on the inside of the rim so that I could screw in a filter?

A: According to the manufacturer, the Urth Adapter Ring for Magnetic Lens Filters (52mm) have a magnetic front threading. They are designed to be used with magnetic filters of the same size. However, they do state that if you are looking to use a magnetic filter and a screw mount filter at the same time, you may certainly do so. You may stack magnetic filters and screw-on filters. All our filters are double-threaded, which means they have back and front threads so you can stack filters of the same thread size. Just make sure to put the screw on filter first, followed by the magnetic adapter ring (or the magnetic UV filter), and then the magnetic filter you want to use. However, stacking too many filters together can cause vignetting so we would not recommend stacking more than two filters together.
