K&F ConceptMatte Box with Two 4 x5.65" Filter Trays, Camera Matte Box with Carbon Top Flag, 5 Adapter Rings 67mm/ 72mm/ 77mm/ 82mm/ 95mm Lenses, Compatible with SmallRig NISI TIFFEN Filter Accessory

*EDIT*The actual quality of the product is excellent, I'm really impressed, and I was able to finally use mine yesterday. The system works pretty slick and i was more than impressed. popping between ND filter was super easy, and the fact you can house two ND filters at the same time means you don't need to have an insane collection of them, I was able to get everything I wanted from 3ND filters on what I would consider to be a very sunny day.The original orders had been broken, but I don't think this was a product 'fault' but very obviously a heavy handed user returning the item and Amazon simply redistributing it. I genuinely can't blame K&F for that.What has really surprised me is K&F Concept have been AMAZING at making the inconvenience right. The customer service is excellent and have been on it since they learnt of issue. I must say I found this refreshing and very reassuring, and gives me a lot of confidence in their products.*ORIGINAL REVIEW*Ordered two so far. Both had a broken lens ring adjuster. About to order a third hoping that this one is ok but what I’ve seen of it so far is pretty impressive. Looks cool and can't wait for it to arrive.

Wonderful l loves it

The value for money for this thing is great. I love that I can stack 2x NDs. This isn't a thing on some of the others that are similarly priced. It's relatively light and super easy to set up and to swap out the lenses. Quality of the materials seem good too. K&F rarely disappoint in that regard to be fair. It came with enough step up rings to fit my lens too!

K&F’s Matte Box for cameras ships inside a protective carry case and with a comprehensive set of lens adaptors that should work for most setups. There is a set of adaptors to thread onto camera filter threads. These cover most lenses I own with 67,72,77,82 and a 95mm. The matte box has a few threaded and Arri pin locator style connectors on it that you could use to mount to your rig rather than lens. I don’t know I would attach accessories to it whilst it hangs off a lens. The design of the lens adaptors mean I can’ t uses them with my variable size lens thread adjustor as they need some space to go back behind the threads. They did spin easily onto my lens; and the large greppable surface around the adaptors makes it easy to remove them.This box only has a vertical carbon fibre (to keep the weight down) barn door, it doesn’t have any French flags. Thanks to mounting to the lens, you can use the door from above or below to protect from stray light. I setup an example showing light hitting the lens and the door blocking it in the photos. The door acts as the cover to protect your lens/ filter when in use. The door has a tightening knob that will keep it in place.The filter holder happily holds my 100 x 150mm filters; and has a good mechanism to hold them in place. I’m not sure if my filters are thicker than normal but I found the filter holder can only hold one filter. I can’t say the same about the mechanism that attaches to the lens adaptor; I found it impossible to lock things in place on an 82mm threaded lens.The matte box is quick heavy; my scales weighing it in at around 213g (photo attached - without a filter.) For outdoor shooting on a summer day, it’s a step up from a lens hood as it gives you more control over the light hitting the lens; it also makes it easy to use 100x150mm filters without needing other adaptors. It’s a great starter matte box; from the price, the lightweight not making your arms droop on a long day. If your project has you shooting in bright sunlight for hours you may want one with more options to block light (or use some black paper and tape to get what you need.)K&F have really started to produce some excellent products this year; this matte box isn’t perfect, but it does a good job; and for a reasonable amount of weight.

£60 at time of reviewI rarely hand out five stars... Great little matte box, nice and light weight, but feels good and strong, plus comes with an excellent storage case. Comes with 67, 72, 77, 82 & 95mm adapter rings, that simply screw onto the front of your lens, then to add the matte box, simply place it onto the ring, level and tighten the lever on the side.Filters are held in place by a filter frame, you simply slide them into place, as they drop into place and aren’t sitting in a groove the frame will accommodate 1.8mm & 2mm filters without rattling issues, the frame itself slides in from the left and clicks into pace, you can also stack filter frames. The top flag can also be locked into position and locked closed.A really neat feature, the adapter rings have the same size filter threads on their front face, allowing additional circular filters to be added directly to the front of the lens, also means when you move from place to place you can attach your lens cap too.As the filter itself sits about 5cm in front of the lens you’ll need to consider the physical size of your lens and focal length. A lens as wide as a 20mm will likely suffer vignetting… not a fault of the box, just something to consider.For £60 I’d say this is excellent value for money, it’s very nicely madeHope my review was helpful
