Related Questions and Answers

Q: 1. 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: 2. Is the outside diameter of the larger part 95mm? Or does that refer to the inside diameter?

A: The filter has an inside thread diameter of 82mm and an outside thread diameter of 95mm.

Q: 3. Can this be connected directly to a generator?

A: Yes, the CyberPower OL6KSTF Step-Down Transformer can be connected directly to a generator.

Q: 4. Will this fit on the older style Chrosziel matte boxes? I have the CLWAH-4,5

A: Not that we are aware of. This product is only listed as compatible with the MB-450 Series Matte Box.

Q: 5. Could I use this with the ARRI LMB 4x5 with a 114mm clamp on back?

A: No, the Vocas 114mm to 88mm Step-Down Ring for MB-215/216 & MB-255/256 is designed to be used with Vocas matte boxes only.

Q: 6. Can I use filters 4x5.65 in this Clip on?

A: no this will only support 4x4 filters

Q: 7. Does this fit Cabrio 19-90?

A: Yes it does. Lenses like the Fujinon ZK19-90mm T2.9 Cabrio Premier Lens (PL Mount), B&H # FUZK47X19, have a 114mm front diameter, which is the kind of attachment this adapter provides.

Q: 8. will the step down rings for the Wooden UMB-1 work with this?

A: I'm afraid not, this product is designed for Bright Tangerine Matte Boxes and may not work with Wooden products. We do have B&H # WO204900 which is Universal Matte Box Cloth Donut specifically for the UMB-1.https://bhpho.to/2NKCwNq

Q: 9. 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: 10. Can this ring be used to mount a 58mm filter on an leica series 7 lens? for example Summicron 90mm SN 2462538

A: No, this ring is to attach to a lens with 58mm filter threads.

[143 mm] I know step down rings are very simple pieces of metal. But I was relieved to see that they fit well on the lens And my filter fits well on the inside ring. (I have seen worse...) 5

[143 mm] Works great on my Nikon D750 with Nikon 28-300 lens (normal 77mm filter mount). Can use all my smaller 52mm filters. No vignetting as long as you use the DX in-camera crop option, found on the D750 menu. You should not use these filters in FX Full-Frame mode. 5

[Plastic] I just switched video cameras and had add on lenses (wide and telephoto) from the old camera I wanted to use. The step down ring saved the day. 5

[143 mm] The item was just as described and shipping was very fast. 5

[143 mm] This ring threads much easier than other rings I have used. It seats quickly without any fumbling around to get it positioned, and treads in just a few turns, a real plus when you're running and gunning and don't have a lot of time. 5

[143 mm] Bought these step down rings to use on various lenses that i have to fit the Raynok 250 Macro lens, the rings came in great condition, delivery was well and truely on time and the products are value for money. So thank you. :) 5

[143 mm] Great step down ring that threads easily. I have a Cavision rod support system as well and its never steered me wrong. So naturally when I needed a step down ring for my Jag35XL, Cavision was my first choice. Serves its purpose and keeps my set up uniform. 5

[143 mm] Not much to this device, but it works as advertised. I purchased this product to step down from the 82mm fitting on Fujinon TH16x5.5BRMU lens that comes with the JVC GY-HD100U camera to a 72mm Cavision PWA06X72 wide angle adapter. Fit is clean and result is low profile. 5

[143 mm] Sensei makes very good rings, I bought all of them UP and Down. They are very accurate and well finished so that rarely they get stuck. This one was to mount a 77 mm Marumi in front of a Sigma 50-500mm (first version). Despite the different thread pitch the Sensei was able to screw in for half turn and was reliable. 5
