[5.7 x 4 x 1.7"] I recently bot this a couple of weeks ago. I used it on a shoot and it worked amazingly. For its price, it really helped with getting out shadows and getting rid of any unwanted light just like any other Matte box but simply for cheaper. Whilst it functions extremely well, something that is annoying about is that I had to buy a step up ring so that it could fit onto my camera which cost another $15 but it was completely worth it. I would recommend it to anyone who is currently in the first stages of learning how to rig out cameras as it really helps people learn about the usefulness of Matte Boxes

[5.7 x 4 x 1.7"] I also have a smaller good matte box from Genus, but I love this carbon fiber mattebox from Lanparte. It can be used with a wide range of lenses from CP PL to DSLR lenses with a lot of diameter adaptors (donuts) included as well as a nun's jacket. All articulations are precisely engineered. Can be adjusted quickly in length and height to fit many configurations. I use it with a Black Magic Cinema Camera, a Nikon D800 and a GH4 with either a Sigma 18-35 or a Sony professional B4 zoom. Not a cheap one, but stands the quality of Chrossziel with a more reasonable tag. All knobs are positionned at the right place and the filter trays are very solid and handy.

[5.7 x 4 x 1.7"] I had to exchange the first one I received due to a manufacturing default, the replacement is excellent. Really excellent quality, feels comparable to the Arri matte boxes I've used extensively in the past, but at a fraction of the price. Note that it does come with both nuns knickers and fixed doughnut rings for a variety of lens sizes. My only complaint would be that it's slightly heavier than expected (given the carbon fibre), but no more so that other professional solutions.

[0.2 lb] Here is a real matte box. The right size and weight for small modern cameras. There are, to be fair, a couple of small annoyances, but they are easily overcome with some minor engineering. Considering that no two camera systems are identical, Cavision has done a great job. Two filter slots are enough (one rotates), the flags are fine and work well. Donuts would be good, but can be made; the nun's knickers are OK for most lenses. I had used this on a shoot, loved it, bought one...and will by another...

[0.2 lb] Ive yet to use this on a shoot, but first impressions are great! All as described and works well with my 1dx mark II and smallrig cage and rods etc. Very happy.

[0.2 lb] Great build quality! I use this with my C300 MK III and although it has built in ND the two trays of the matte box allow for a circular polarizer and a pro mist filter when I want/need them.
It’s fully adjustable and comes with donuts and knickers to block out any and all light.

[0.2 lb] Despite being largely of ABS construction, this matte box is surprisingly sturdy. Everything locks and tightens firmly and stays in place during use. So far I'm very impressed with this unit, it provides affordable, light weight light control, ideal for cameras with lenses up to 85mm diameter. Also, I'm from the UK and it arrived from the USA in less than a week. Many thanks B&H.

[5.7 x 4 x 1.7"] Well designed and well constructed. Thoughtful, considerate and nimble.
Beyond the quality of this one product I'd like to note how great this company is. I recently had a camera hit the ground on set. Shape didn't just respond to my email and sell me the henge that took the brunt of the fall, they called me, two or three times. They wanted to make sure they got me what I needed, not more, in a timely manner. Their attention and concern has made a fan into a loyal costumer for life.

[0.2 lb] Well made from good materials, fits well on my rig, and I really like the swing away option when changing lenses and so forth. The hard case is a nice bonus as well.

[5.7 x 4 x 1.7"] decent price
