Q: 5. 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.

Q: 9. Does anyone just buy this adapter ring, and buy cheaper step up rings for your lenses with smaller front diameters? Essentially making all of your smaller lenses a 82mm front thread so you don't have to buy a bunch of $55 adapters?

A: This solution works if you're not attaching the adapter ring with a step-up ring to a wide-angle lens. I your lens is 18mm or wider on a full-frame, you may get vignetting on the corners. You should buy the wide-angle adapter rings for any wide-angle lens you have and cheaper step-up rings for your other lenses. Of course, this isn't as convenient as having an adapter ring on every lens.
