The 4-stop, 4 x 5.65" Illusion Full-Spectrum ND Filter  from Tilta is a waterproof, oil-resistant, and scratch-resistant nano-coated filter designed for the 4 x 5.65" filter holder supported by the Tilta Mirage matte box. It's also compatible with any matte box that has a 4 x 5.65" filter tray. As a full-spectrum ND filter, it evenly reduces all wavelengths of light, including visible, ultraviolet, and infrared light. The filter is built to uniformly reduce the levels in the light spectrum without significantly affecting the color. The overall spectral curve remains consistent, and light intensity for various colors is proportionally diminished and does not result in color bias.

Q: 1. is there any possible way to change this matte box from rod-attached to a clip-on, attached directly to the lens safely?

A: I have used my MB-T03 as a clamp on to 144mm diameter lenses. You can take the swing away rail mount attachment off with Allen keys. Just don't loose the screws if you want to reattach the rail mount!

Q: 2. will this fit on sigma 50-100 t2?

A: Yes. The following will adapt with the proper rail system attached.

Q: 3. Is this height adjustable?

A: yes it has about 2-3 cm adjustable height to allow slight variation of clearances between lens and rails. It's a great looking and well build botte box

Q: 4. What's the widest lens you can use with this without vignetting?

A: It depends on the camera and the lens. But probably a 10mm on a Super35 camera or a 14mm on a full frame camera would work. Unfortunately, there are so many variations it is impossible to list them all and only an actual test will confirm.

Q: 5. will this work with fujinon mk18‑55mm t2.9? It seems like there would be a 5mm gap

A: The Fujinon MK18-55mm T2.9 Lens, B&H # FUMK1855, has an 85mm front diameter. This Matte Box has an opening that accommodates lenses up to 114mm in diameter. To use this Matte Box with that lens you will need a 15mm base plate to attach the matte box to. Once you have such a product the Matte Box includes a Fabric Lens Donut which you would use to block out any light that might slip in thanks to the difference in size between the Matte Box and Lens.

Q: 8. I just want to make sure this will work with a 134mm lens. The Zeiss 50mm makro is 134mm and that is what I want it to work with. Will it?

A: The MB-T03 will not accommodate the Zeiss Compact Prime CP.2 50mm/T2.1 Makro-Planar T, however our MB-T04 will work.

Q: 9. Hi, Are there one or two rotating filter stages ? The description above says two but online reviews state there is only one... is this a newer model/design ?

A: there is one that rotates and the other is stationary

Q: 10. Can the MB-T03 use 100x100x2mm filters or strictly the 4"x4"x4mm filters?
