I have no prior experience with matte boxes, so I had no idea what to expect with this K&F Concept Mini Matte Box. First of all, this is a very well made product. Most of the matte box appears to be made of aluminum, with a few small plastic parts and the top and side wings made of carbon fiber. This makes the entire unit very light; I barely noticed the difference in weight with this mounted to my camera. The adjusting knobs work smoothly, and the lens adapter screwed smoothly onto my lens. It was also very easy to then mount the matte box onto the adapter after screwing the adapter to the lens. I like that the matte box comes with a variety of adapters to fit common lens sizes; it has adapters for the two sizes I use most, 72mm and 95mm. Finally, I like the very nice hard case that comes with the matte box.

I am not at all sure what I will be able to do with this device. I know that matte boxes are most commonly used with video, which I rarely shoot, but I can already see potential uses for still photography. I experimented with it a little, and I can see already that it offers better control over unwanted light than a lens hood. The matte box has filter holders for rectangular filters, but I already have a large selection of round filters, so I don't anticipate using the filter holders. However, I do see a reason to use this matte box with some round filters. For example, I used it with a variable ND filter that won't work with a lens hood. With this matte box, I can use the VND filter and get better control over unwanted light than I would if I could use a lens hood. The matte box isn't something I will use all the time, but I can see times when it will be just the thing I need.

Overall, the K&F Concept Mini Matte Box is an excellent product that fills a niche for photography hobbyists. Just as it isn't an item to use every day, it isn't an item for every photographer. If a matte box is something a photographer wants, the K&F Concept Mini Matte Box is a great choice. I recommend it and give it five stars.
