Matte Box Kit+ND8 Square Filter Compatible with Two 4x5.65" Square Filters Includes 67/72/77/82/95mm Adapter Rings Nano-Xcel Series

Nice mini mattebox and filter combo. As long as you don't need strong side occlusion from light the matte box works pretty well. The flag is easy to adjust and tighten. The adapter rings can be slightly finicky but once you get the hang of them it's easy to use and swap the matte box. The bottom has a thread that can be used to put the matte box on rails.

The matte box is not super light. If you have a very long and heavy lens and a camera with a loose lens mount you may run into some issues with the lens sagging. If so you should put it on rails. In my tests it did well on any quality lens i tried it on.

The black mist 1/4 filter is very nice. Look at the test photos. The diffusion is a great, gentle strength that softens highlights and lowers contrast just by a little. Makes the image slightly more dreamy while still retaining a good amount of sharpness.

This mini matte box from brand K&F CONCEPT is a substantially premium upgrade over traditional round ND filters for your DSLR or mirrorless camera.

This system makes your entire setup look wholly professional and really plays a convincing role that you are ready to take on tasks for clients. But is not just for appearances as I now have the ability to diffuse and reduce light in a large square profile with variable ND blocks that are interchangeable but also layer-able.

Overall, I can't imagine using my video rig without this system now, and I hope K&F CONCEPT offers other interchangeable filter sheets for this matte box in the future. 5 stars.

I love it it works well and looks well built

The K&F Concept mini matte box is delivered in a well-crafted box.
Inside we have
a hard EVA case
The mini matte box
Five adapter rings

and a mini matte box made of carbon fiber, equipped with a hood in the upper part and two rectangular filter holders where we can mount various filters from neutral to ND.
The five rings range from 67 mm to 95 mm.
The peculiarity and functionality of these adapter rings is the fact that they are equipped with double threads.
External to be mounted on the lens and internal to mount the classic circular filters inside the matte box.
So we have the possibility to use whatever type of filter we have in our kit.
The supplied hard case is really well made, but above all it is great for transporting and storing the matte box.
I am very satisfied and recommend it.
Value for money is really great.
I hope I was useful to you in choosing the product.

I shouldn't be surprised by the great value and quality of this Matte Box by K & F. There is nothing about it that I find concerning and for the money I think it's excellent. If there was one option I would ask to be made available, it would be an adapter that would also allow 100 x 100 square filters to be used, but alas, that doesn't seem to be an available option at this time of writing. Maybe I'll try and make something for myself as I really do like this matte box and want to use my existing square filters with it.

While this will accommodate two 4 x 5.65 filters in addition to a circular filter, there isn't much room if a lens ring is needed for the circular filter. Basically I've found the adapter ring removes the usage of the first inner square rail. That I think is a minor point, but evidently slim circular filters are best if this matte box is to be used at full capacity.

Awesome quality mini matte box from K&F concept! It's made of high quality metal and carbon. The box allows to use 2 square filters at the same time. The filters are sits in the metal frame, but can be swapped easily. The kit comes with 5 different lens adapters. Everything is packed in hard shell case. I was surprised that all parts are made so good and this kit cost twice less then other brands but quality is top notch!

I thought this matte box could help my photography, but I was very disappointed when on opening the box, there are no instructions.

Googles the item and found a few videos which really didn't help much but I got the gist of it.

Most matte boxes have top and side flaps, This only has a top one so you are a bit limited on keeping reflections away from the camera lens.

Once you realise how to gt the side filter trays out - there a catch to the side you are presented with two trays, but no filters. Shame but these can be bought online.

The matte box comes with a number of filters to screw mount onto your lens.

The interesting thing about this adapter set is its versatility and expandability.
It comes with 5 mounting holders for different types of cameras. This actually covers the most common sizes and, as far as I know, fits almost all SLR cameras.
The set also includes a pretty good ND8 4X5.65 gray filter.
This is used to darken bright subjects in particular and also improves the intensity of such recordings.
There is also a sturdy case for storing the set. Instructions are not available, but the system is actually self-explanatory.
As already described above, the most interesting thing for me here is the versatility. There are various options for attaching holders or even handles, and of course using other filters.
Overall, a very good set for accommodating many camera systems. Expandable and comes with a really good gray filter. The existing light cover is simple but functional and everything can be transported in the sturdy case provided. The workmanship is very good and without defects. I would be happy to recommend it to others.

The K&F Mini Matte Box incorporates unique, useful features normally found in more expensive matte boxes; specifically, two dedicated 4” x 5.65” filter holders, and the ability to attach circular filters to the various lens adapter rings, of which five sizes are included. This allows for the use of a combination of both filter types concurrently. So, for example, placing a three stop 4 x 5.65 ND filter in front of a 1 – 5 stop VND filter, effectively increases the VNDs range to 5 – 9 stops, very useful for shooting video in a bright situation. This, in terms of my work, provides a broad range of versatility when it comes to the use of filters. As I write this it is being offered with a 20% coupon, bringing its price to $52. With or without the discount, it’s a lot of Mini Matte Box with a lot of versatility at its price point.

Other than the knurled locking knob assemblies for holding the flag in position and attaching the Matte Box to a lens adapter ring, the Matte Box is made entirely from a matte finished carbon fiber, for a very lightweight assembly. The two locking knobs are easily accessible, incorporating simple, but effective mechanisms.

The rectangular filter pivoting lock mechanism was new to me, as was the use of the rectangular filter holders. In fact, they caused me some frustration until I figured out that in order to insert a filter, the tab must be pulled away from the filter in the lengthwise direction. I wasn’t comprehending the illustration and kept trying to pinch it, to no avail. Once I figured that out, inserting filters into the holders and then the holders into the Matte Box went smoothly. When using two filters, or in my case, any filters, be careful releasing the associated lock; the outer filter is designed to pop up when released, but could pop out if being held in an accommodating orientation.

As K&F asserts, the Matte Box incorporates 1/4' and 3/8” threads and a cold shoe. The interior is also lined with black felt to reduce reflections, a thoughtful touch. K&F also says to expect future expandability to include side and rail extension boards, that I take to mean the addition of side flags. As such, providing more versatile light control; I’ve never understood the logic of just one flag on a Matte Box, considering that more than one light may be in use or that reflections can come from any angle. As a suggestion to K&F Concept, if more flags are created in the course of expandability, coat their interior surfaces with a non-reflective matt black material.

K&F delivers the Matt Box with a quality hard case to fit and protect it and the filter adapters. I have no criticism but plenty of enthusiasm for K&F Concepts new Mini Matte; it is a filter holder and a means of light control for both video and still photography.
