I bought these so that I could see the fox that were killing my chickens and cats at night so that I could shoot them. I no longer have a fix problem! These were simple to use right out of box. I've tried some before that were just so complicated never could figure them out but these are self explanatory.

Does the job: protects the lens of the lens. Matte appearance and a bit rough feel, but it's just an aesthetic detail.

I've seen various films that noted the use of diffusers. I really compared a lot of black matte filters. This one is perfect. I get the softening without noticing it. This is really a high quality filter. I am very happy with it.

This is a great product. Easy installation. I love the elegant matte black. This will definitely keep my kids out of my room

The camera stand is made of sturdy material and has a high quality of matte surface!! The most impressive me it is the camera stand has multiple adjustable tight handles that allow me taking product pictures from a wide angle.

I bought it for its minimalism. All matte black and I love it. With my Nikon Ai F lenses it suits luxury

add a clarification on the product after use. I'm very happy with the Nikon 35 1.8DX on this adapter.. which I thought was a bit thick.. I expected some loss of brightness. Since there is nothing in the product details, I tried to ask K&F about it: no answer... :( Well, I did the measurements myself... with the same aperture on a sensor with the same resolution, we go with the adapter from 1 /800 to 1/500.. so 3/4 of an additional f-stop my 1.8 Nikon becomes a 2.2... a 2.8 becomes a 3.5 the product is excellent but good to know this loss of brightness ( would have liked to see it noted). As with the extended rings, the lens attached does not lose any sharpness I was waiting to receive it, at least not expecting the best... Surprise; the product is heavy, well finished (I have already extended All plastic rings) I grab my XM1, I pull out my fixed AFD focal lengths... the 24... that becomes a 36... and the 35/2 a 53mm my first attempts at shooting don't work: he you have to Select "shoot without lens" in the xm1 settings, I continue to shoot, excellent the system of" ; "Rand" on the screen when the MAP is ready, (I tested at 1.8-2 to verify this map, on the computer the map is actually correct). The contrast system is only really apparent at a wide aperture... As with some old cameras, open the aperture card wide and stop before shooting with other cameras in range that also have viewfinders. It might be easier to focus manually: the ring also allows you to do glare, you do that "at your discretion", but it's great to have. The 35 1.8Dx is very good at 1.8 for anything that doesn't need an ultra-fast card (j) I've tried portraits of my dogs... that move... well, manual focus on the XM1 screen remains quick and accurate ), for anyone who has a quality focal length stash that doesn't want to buy new ones that aren't necessarily better in terms of sharpness (no choice on Xmount Mount). I recommend this ring in addition, very affordable I am very happy with this surprise purchase, all my Nikon lenses are reworked with this camera

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.
