Neewer Plastic 15 mm Rail Rods Matte Box for Canon Nikon Sony Fujifilm Olympus Panasonic DSLR Camera,Camcorder Video Movie Film Making System(Red)

Brilliant for what it is. I have used these for years and considering how light and cheap these are, they last a long time.

This is not really a matte-box, which is a bellows like device and usually very expensive as they also take filters. As barn doors, these fulfil their purpose and are very good value. They fit to the rails of the Neewer small rig, with a firm fit and the screw knobs keep them tight on the rails: these knobs are the Achilles heel of the product, I suspect, as they feel very cheep and insubstantial: they work and you can change them. One reviewer made the point that their camera tripod screw is not placed centrally under the lens, so check for this. Otherwise they are adjustable for lens length and for height. They are adjustable so should keep extraneous light from the front element of your lens: especially important if you are carrying a video light on your rig.

It's not a matte box, but does what it's intended to do v.well.

For the money, I can’t complain. It works fine and does its job.

Great accessory to my small rig cages. For the price it's great

Great addition to the neewer rig fits really weel
