The Fabric Lens Donut from Tilta, also referred to as "Nun's Knickers", attaches directly to either the MB-T03 or MB-T05 matte box and is used to prevent light from leaking around the lens from behind the camera and degrading your image. The fabric donut can be used with lenses with an outside front diameter between 90 and 100mm. It is flexible, allowing you to work with lenses that change length when you focus or zoom without sacrificing the light-blocking effect. The donut slips around the front of your lens, and the integrated elastic band snugs it tight.

Q: 1. does this fit onto the title MB-T04 as well?

A: No, it does not, sorry

Q: 2. Will this work with the O Box's bellows ring?

A: Yes, the Bright Tangerine Black Hole Mini Rubber Donut will work with the O Box bellows ring.

Q: 3. Will this work with the Tiffen 138mm Variable ND for Matte Boxes? (Product Number BH #TI138VNDMBM)

A: The Bright Tangerine Black Hole Mini Rubber Donut for Matte Boxes with 114mm Rear Opening (B&H# BRB12501077) is a rubber donut that is not designed to accept the insertion of any filters into it. That includes the VND filter in the Tiffen 138mm Variable ND in Matte Box-Mountable Rubber Donut for 143mm Openings (B&H# TI138VNDMBM). While it may be possible on a DIY basis to disassemble the parts and engineer a means by which to connect them, we cannot recommend nor endorse doing so. Just for the sake of clarity, the Tiffen 138mm Variable ND in Matte Box-Mountable Rubber Donut for 143mm Openings (B&H# TI138VNDMBM) includes both the rubber donut and the Tiffen ND filter within it. It is a one-piece unit that is designed as a replacement rubber donut for the rubber donut that would normally go with certain compatible matte boxes. (Please see the compatibility list at the end of the Tiffen product's Overview section.) As such, the VND incorporated into the Tifffen product is not designed to be removed and then installed in another donut such as the Bright Tangerine Black Hole Mini Rubber Donut for Matte Boxes with 114mm Rear Opening (B&H# BRB12501077).

Q: 4. Elastic on both sides?

A: Hello,Both sides are indeed elastic. Also, it bears noting that the side that attaches to the matte box has a much wider opening than the side that covers the lens.

Q: 5. With fabric on both sides, wouldn't this be able to fit on the MB12 Tilta matte box? I need to cover 5mm gap from 95mm-90.

A: The reason the Tilta TSP-023 (Nun's Knickers) work on the MB-T03 and MB-T05 matte box is because those matte boxes have a lip that catches the elastic band. The Tilta MB-T12 does not have this lip. Therefore, there is not an effective way to attach it to the matte box.

Q: 6. Can I use lenses with a diameter of 49mm in this mattebox or would there be any problem in?

A: Yes you can. This does have a universal Knickers for smaller lenses to block out light. You will need to have this matte box mounted on to a 15mm baseplate though.

Q: 7. What dimensions are the adapter rings?

A: Here's the dimensions of the rings included with the matte box:64mm, 68mm, 72mm, 82mm

Q: 8. Does this attach via pressure from the donut or a clamp on the matte box? I'm wondering if it will work with the Wooden Camera Zip Box Pro Swing Away, which doesn't have a clamp.

A: The Bright Tangerine Black Hole Mini Rubber Donut for Matte Boxes with 114mm Rear Opening will also work with the Wooden Camera Zip Box Pro Swing Away since it has a 114mm fitting.

Q: 9. Will this fit an Arri MMB-2 matte box?

A: If your MMB-2 has a 114mm opening then yes it will fit.

Q: 10. Will this fit the Redrock Micro Matte Box?

A: No, the Bright Tangerine Black Hole Mini Rubber Donut for Matte Boxes with 114mm Rear Opening will not fit the Redrock Micro Matte Box.
