I chose this neck mount phone holder with clamp style grip because I don't have a magnetic case and didn't want to also have to purchase a new phone case. Love that you can pivot the clamp to horizontal or vertical. The neck portion is soft around the neck and the piece that sits on the chest isn't uncomfortable.

The K&F Concept CPL filter for cell phone cameras has convinced me overall.

The filter offers solid workmanship and ensures significantly better photos, especially in difficult lighting conditions and reflections.

The clamp mount is easy to use and holds securely on the phone. I find the magnetic mount of the lens particularly practical, which makes attaching and removing it very convenient.

A small disadvantage is that the filter is sometimes a little difficult to align, and with thicker cell phone cases the clamp mount can be a little wobbly.

Despite this, I am very satisfied with the image quality and handling. A good product that I can recommend to all smartphone photographers!

I took this ring to mount an M42 Helios on my Z6 and it's perfect, there is no play between the two bindings. Light and compact, the material is the usual for most of the rings they make, a recommended product, the only flaw in my opinion is the price a bit excessive.

First impressions: - good looking - fine workmanship - matte interior finish (light doesn't jump in) - smooth conformance to camera body - smooth shift rotating One ring - comes in an unsealed hard case and nothing else on it - out of the box with any vintage Nikon mount usable lenses - orange ring gives the looks to the whole camera setup - the adapter fits harder on the lenses (needs to be attached) - focus is based more on the depth of field (FOD) difference in the picture frame - it works more like zone focusing and precession focus zones are heavy to reach - metal mount on lens side and (I think it's still a metal) black plastic which looks nice, camera charcoal mount (it's passive adapter and therefore no electrical communication between lens and camera) - light doesn't get through the adapter into the Barrel (sealed fit) - it should come with end caps to the adapter to keep dust out when not in use - for the money I paid I like experimenting with my old lenses on the Sony mirrorless body

NIK-NIK Z-Ring single ring, without coupling: Nikon Z-mount male mount, Nikon F-mount mount female for pre-AI, AI and AIS lenses. You can therefore use old lenses whose pre-AI bayonet can damage the FTZ. No problem with a Nikon Z: the light is measured at the actual aperture and manual focusing is done with colored markings in the viewfinder. So I use my old 50mm 1.4, my 20mm 3.5 UD, my 300 4.5 Nikkor H which are all 50 years old... and my AI 50.135 and 200. The ring is well built, no play and we have infinity. NIK(G)-NIK Z-Ring Attention, for Nikon G lenses you need the Nikon FTZ or the NIK(G)-NIK Z-Ring, which allows you to maneuver the aperture, which do not have a ring on the lens. With the NIK-NIK Z, the G lens remains closed at the smallest aperture, so no modification is possible. Attention should also be paid to the IBIS: you need to record the focal length of the manual lens and specify it when using the camera: vibration compensation is much more effective if the Z camera knows the focal length.

The ring does what it is told. I deduct one star for the fact that I had to readjust the mount myself so that the aperture and focus indicator of my lenses is straight and not on the side.

This adapter is used to use an A-mount lens on E-mount cameras (in my case a Sony Alpha 6100).
The construction is good, it weighs just enough to notice that it is a quality product, it works perfectly.

You have to keep in mind that with the adapter you will have to use everything manually, that is, manual focus is obvious, but something I did not know is that the adapter comes with a ring to close or open the diaphragm but it does not show the step diaphragm (1.8, 2.8, 3.5, etc).
In the camera as you move the ring it will not appear which diaphragm is being used either, specifically in my camera it says F/0.0, even so, you can use the aperture priority mode and the camera calculates the shutter speed without problems.

I needed a light to go with my webcam and chose this as I liked the flexibility of having a tripod as well as a separate clamp to fix on top of the monitor. The lamp has natural and other light types which allows you to choose whatever works best with your skin colour. You can also dim the loght as required with the built in on/ff and dimmer switch built into the lead.

Super easy to install and use.
