Strong enough for video setup (Teleprompter, camera, field monitor, batteries, V-Mount battery. Lightweight and tough. It comes assembled. (Teleprompter, camera, and wheels not included).

I'm really very happy with the purchase, this adapter is amazing, the membrane ring is very fluid. The good thing is that the system for opening the aperture works perfectly with Nikkor lenses, Nikon G, Tamron (Nikon mount), Sigma (Nikon mount), something I didn't find in my old adapters (they only worked with Nikon brand lenses). Besides the excellent functionality, it is also easy on the eye. It's not very heavy, but not too light either, suggesting the use of "full" materials.

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.

A ring that does the job without a problem. Well made, with a nice satin finish, I use it to mount a Helios on my X-T4. I did not detect any play, and the assembly-disassembly is done without worries. The focus on infinity is effective, no problem either on this side. The orange decoration is a bad taste, at least on a Fuji. Apart from this trifle, I recommend this ring.

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.
