Matte Box for 15mm Standard Rail Rods for Canon Sony Panasonic Nikon Fujifilm Olympus Cameras Camcorder Lenses Diameter Less Than 85mm with Height Adjustable for Different Camera Lenses

Never liked clunky barn doors and big unclosable flags. This one is LIGHT and well made. Fits the carbon 15mm sticks perfectly and tightens down. I would buy it again. It's not a PRICE thing—it's a coolness thing. IMO.

Very lightweight, great value and does what is needed which is to reduce or prevent glare when shooting outdoor facing at angle toward the sun.

This product would be ideal if the design had moved the flag attachments forward like a normal barn door set. With the current positioning the flags cannot close over the lens to go in the case. You have to disassemble it every time.

The rail and riser parts are aluminum. The matte box and flags are plastic. Fits on 60mm wide/15mm rod systems. The flags snap onto the matte box, they stay put when you adjust, very nicely designed and built. Slides smooth on rails.

I’m impressed with the build of this matte box for only costing $14. However, I think it’s properly priced. If it were more expensive, I’d be looking at higher end boxes. I use this one just for a back up or when I need to travel light.

For the price, and effectiveness, it’s fine. A little flimsy, kind of moved in a breeze but nothing gaffers tape couldnt handle. It’s good tho, in a pinch

It doesn't fit the standard 15mm rail rod system. I have a pair of 15mm rods, and a set of matching clamps/adapters, from different brands, and they work together well. However this matte box is very tight when I put it on, even when all screws are loosen. And even worse, when this matte box is put on the rail, it becomes very difficult to put on other clamps.I really hope I could use this matte box because of its attractive price and large diameter, but it's just not usable. It simply doesn't fit on the 15mm rail system.

I actually bought two of these to go with my BMPCC4k cameras. These guys are sturdy and very light weight. I would have given it 5 stars but I left one in of these in my pelican suitcase and the next morning one of the blades was a little bent. I set a weight on it for a few hours and it went right back to normal. It's definitely not a deal breaker but. I will be more cautious moving forward about where I keep it so the blades don't get bent out of shape.
