Q: 1. Is this adapter for the Novoflexar rapid focus system lenses made for Novoflex since 60's till 90's?

A: No, this Novoflex Adapter for Novoflex A Mount to Canon EOS M Cameras was created much more recently in order to attach Sony Alpha DSLR A-mount lenses onto Canon EOS-M mirrorless cameras. Both have not been around as long as the 1960's through 1990's. They are much younger systems than that.

Q: 2. Can this function as a step down ring (114-82mm) on the front of the NiSi 114mm Shatter-Proof Protector Filter?

A: The Movcam 114:95mm Step-Down Ring for 114mm Threaded Matte Box is not compatible with the NiSi 114mm Shatter-Proof Protector Filter.

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.

Q: 4. What’s the outer diameter of this ring?

A: Our sources show that the diameter would be 77mm, but since the manufacturer does not explicitly provide this spec, we would recommend verifying with them before purchasing: https://bit.ly/2J8yZL7

Q: 10. I have a 300-600mm Tamron lens and have a 77mm Cokin Z-Pro Series Filter Holder Adapter Ring. Is this what I could use on my 95mm lens?

A: You cannot. This product is specifically for Wide Angle Attachments. Using a 77mm filter system on a lens with a 95mm thread will be very difficult, there may be vignetting caused by using such a smaller system on a larger one and we do not recommend it.
