A: According to Tilta the maximum size of the MB-T15 is 85mm meaning you could use a step up ring, but you would need a pretty long focal length to prevent vignetting. We do not recommend this matte box for a 114mm diameter cinema lens.

Q: 6. Will this matte box fit a Sigma 24-70mm zoom lens?

A: That will depend on the exact model of Sigma 24-70mm lens you have. That being said this systems comes with 67mm. 72mm, 77mm and 82mm adapter rings. If you have the Sigma 24-70mm f/2.8 DG OS HSM Art Lens for Canon EF that lens has an 82mm filter thread and will work with this matte box. You will just need to double check the exact model you have and see what filter thread it offers.

Q: 9. Will this support 4x4 filters?

A: I just tried a 4x4 filter and it technically fit, but it doesn't cover the whole area so it only works at roughly the full-frame equivalent of 35mm and longer. And even then, there could be issues. There's a little dimple on the adapter rings so you can't just move the matte box/filter closer to the lens.

Q: 10. Is it the same deflector plate regardless of size of the Rapid Box?

A: The 20 and 26 speedlight Rapid boxes use the smaller 2030DP while the 36 and 48 studio versions of the Rapid box suggest the larger 2040DP. The speedlight Duo version could use either, though I prefer the larger 2040DP for this model.
