Box contents:

- filter holder for 100 mm x 100 mm filter
- adapter ring 67 mm
- adapter ring 72 mm
- adapter ring 77 mm
- 82 mm adapter ring
- padded cardboard box for filter holder

The whole thing makes a very valuable impression overall.
The adapter rings are black anodized aluminum - they are well made, not sharp and the thread can be easily screwed onto the lenses.
In addition to the plastic filter cartridges, the filter holder is also made of black anodized aluminum. Here too, the treatment is excellent. Maybe the quality of the plastic inserts could be better, but this is already complaining at the highest level. The inserts fit all 100mm x 100mm filters with a thickness of 1mm to 2mm.
the packaging was impeccable; Adapters are individually packaged; The portafilter comes in a nice padded cardboard box.
Full points and recommendation for a perfect rectangular filter system at a significantly lower price than some other manufacturers.

The adapter ring is delivered in a plastic bag. Unfortunately there is nothing else. I would have preferred a box. A small storage bag or a plastic case would be even better. The adapter ring is really clean processed. No sharp edges, no burrs. The threads are impeccable and do not snag. There are enough threads on both sides, but not too many. This keeps the ring slim and does not result in any vignetting, at least on my Leica Q2.

The ring comes in a black plastic box which gives the feeling of a neat product. The graft is a bit too hard but once fitted it has no play and works well. It has no contacts, so the focus and aperture must be adjusted manually, but this has already been indicated in the characteristics. It allows me to use some lenses with Minolta - Sony mount on my Canon M5.

Excellent dash cam
Easy to fit the front one
Back one a bit of a fiddle but managed it

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.

Description: The rim of the filter is made of matte black coated aluminum, I assume. The rim itself is actually quite nice. The wide, ridged design around the base of the filter makes it easy to put on and take off. The high index optical glass is in fact nano-coated to protect against water/oils from fingerprints, rain, etc. The glass itself has a slight yellow cast (which you can see in the photo comparison), but this can also be easily corrected using the automatic white balance of your camera or Lightroom.
