Cavision ADU085-D45 Reviews

Unfortunaley it's not a good product.

I attached to a matte box ring and without any use just sitting on a shelf. The adhesive softened and the pleather collar fell off. Luckily I have strong adhesives at home. I cleaned all the residue from the cheap double sided tape and managed to get it back on. I had this for 2 days before it came apart. I don't think anyone who needs this for professional use should order. I would hate to have this fail if I needed it.

Great Little product!

Great Little product! I love that I can use various size lenses with my matte box and not have to worry about having a bag of seperate rings.

Great little Plastic Ring to prevent Stray Light. Works great with the Cavision 3x3 Mattebox. I like it.

Great Little Ring to block stray light for the 3x3 Cavision Mattbox.

Kind of stiff

The material is too stiff to be used as a light shield for any lens that moves in-and-out ( during focus or zoom). Other that than, I found it to be okay.
