Q: 1. I plan to use screw in 112mm on my Sigma 105 1.4, will this step up ring fit? I read on their website, this ring only support their magnetic system. Please kindly double check if this ring can also support normal 112mm screw in. Thanks

A: Yes, the Freewell Magnetic Step-Up Ring (105-112mm) allows you to use the magnetic or threaded 112mm filters.

Q: 2. Would this step-down ring allow me to mount a 95mm filter on a lens with 105mm filter size?

A: Both the outside and inside threads on this have a pitch of 1.0 mm so it will work if your lens and filter threads have a pitch of 1.0 mm. In my experience most brands of 95 mm filters are threaded with this pitch. However 95 mm filters made by Formatt-Hitech have a pitch of 0.75 mm and will not fit.

Q: 3. Are the KW Revolution 112 mm filters in the Nikon 14-24mm f/2.8 Revolution Kit compatible with this 95 to 112 step up ring?

A: The Kase Magnetic Step-Up Ring for Wolverine Magnetic Filters (95 to 112mm) is compatible with the KW Revolution 112 mm filters.

Q: 4. What are the thread pitches on this ring?

A: Although the manufacturer does not publish the thread pitch, threads within this larger size are normally 1.0mm.

Q: 5. What is the total outer diameter of this ring? Would the outer diameter of this step up ring fit snugly into the 105mm opening of my clamp-on matte box?

A: Unfortunately, there are no published measurements we could find at current time for the exact outer diameter, but the "step down" ring that is designed to take your mounting option down to a lower number, should easily mount on an opening that matches that higher number, in this case, your 105mm opening on the matte box.

Q: 6. Is this compatible with the fuji 23mm f/2 wr lens?

A: No it is not. the FUji 23mm F/2 WR lens has a 43mm filter thread you will need a step up ring that matches that (such as a 43-49mm)

Q: 7. 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.

Q: 8. Is this only a step up ring or one can use 95mm Kase ND filter and snap it in directly to this step up?
