Finally found an ND filter which can be installed inside the Smallrig lightweight matte box 2660. I did have to remove the holder frame to make it fit. This can be done by carefully pulling appart the frame sides with the lips. In doing so you can op out the filter while keeping the frame intact. Filter quality seems to be ok and it comes with a very well designed holder with an extraction ribbon which avoids having to touch the surface of the filter when taking it out.

It's made out of really high quality leather and has a magnet to keep it closed. There's a belt loop that I'll probably never use, but there's a metal frame for clipping onto your bag that I'll probably use.

I loved the quality of the materials, all metallic. I looked at many kits but they were all plastic and this one in particular caught my attention from the comments. The truth is that it was a success because any other similar kit does not fall below 300€.The nd1000 optical filter is made of glass and gives a very good quality. The only thing I noticed is that it loses a bit of saturation and the white balance is a little bluish, but when processing the RAW it's easily remedied. You increase the color temperature and saturation and you're done!! (I use a Canon 80d + 16-35 f4's). I imagine each optic will be different. Attached some photos so you can see the difference with filter and without filter. Exposure time on the photo with the 30" filter. If you want to start in the world of filters, for this price don't even think about it. Excellent results.

I don't see any appreciable color cast. So if you want to experiment with proper filters without breaking the bank these are a good buy. The filter cases are beautiful and the overall product presentation/packaging exudes quality.

The quality is convincing. No blurring or color changes. There is a case to go with it. Price performance convinces me completely. Clear purchase recommendation.

The filter works cleanly, the tint is absolutely even and without streaks. I am very satisfied with my decision for this filter.
