Excellent Adapter for Vintage Lenses
I upgraded to a Z-mount system at the beginning of the year. I had two remaining F-mount lenses, both 30+ year old Nikon AF Nikkor lenses (the sort that have an aperture ring, and that use the in-body focus motor). I love both of those lenses, as they’re great and have a lot of character, but I was ready to sell them off because I no longer have a body with the in-body motor, the Nikon FTZ adapter is also quite pricey for two lenses of this type. Spending that kind of money on an adapter for lenses that would be manual-focus only seemed like a poor choice. So I listed the lenses on several sites with the intent to sell them for whatever I could get out of them. It was a wrench to let them go (particularly as they both cover focal lengths I no longer have, and have pseudomacro close-focus options that I really like).Then I found this adapter on Amazon. For this price I figured it was worth a try. After all, I do really like these lenses, and there’s no sense in splashing out a ton of money on an adapter that will require me to manually focus anyway.The build quality of this little gizmo is excellent. Both mounts are aluminum. They fit snugly on both the F mount side and the Z mount side. There is no play whatsoever. They feel totally solid on my camera and my lenses. I’ve set up several “Non-CPU lenses” in the camera’s settings, which allows for the IBIS system to function at the focal length I’m using. While it is kind of a bummer not to have any metadata about my aperture, I expected that.If you, like me, have some older lenses from the film era (AF, AF-D, AI, AIS, etc.) for the venerable Nikon F-mount, this is a REALLY inexpensive way to use them with your new Z series camera. I wouldn’t recommend using it with any of the “G” lenses that don’t have an aperture ring (AF-S, AF-P). But if you don’t mind manually adjusting your aperture and manually focusing your lenses, this is a really nice option. I’ll likely pick up a second one so that I have one for each of these old lenses.Attached is a shot taken with the Nikon AF Nikkor 35-135mm f/3.5-4.5, using this adapter on a Nikon Z5. I’m using the lens in its pseudo-macro close focusing mode (@135mm, f/8, 1/40″ ISO 6400 handheld – see? The IBIS is doing one heck of a job!).

Great for vintage F mount lenses
I bought this for my Nikon Z5 to use vintage Nikon F mount manual lenses. As clearly described in the product listing, this does not pass any electrical contacts and therefore no lens sensing, auto focus, or auto-aperture, which makes it ideal for my manual lenses.I borrowed a fully active Nikon ZTF v1 adapter with the tripod mount, and this Fotasy has a much nicer build quality and feel, and also avoids the tripod mount bump that gets in the way more than I thought it would.After a day of shooting with it, and changing lenses a few times, there’s nothing I would change. I was nervous it might introduce vignetting, but I did not notice any beyond what the lenses already did on my 35mm Nikon FM.Based on this product working as well as it does, I’m going to just stick with this, my existing manual lenses, and Z-mount going forward.If you have newer F mount lenses with auto-focus and auto-aperture, you may want to go with the Nikon adapters, but for manual lenses I prefer this (not to mention being 1/10th the price!)

A simple unpretencious product for manual Nikon AI, AIS lens
I like this adapter for Nikon manual lenses to the Z mount better than many other expensive ones; this one does not support the automatic focus interface (AFS) for focusing; you need to focus the lens manually, but with the Nikon mirrorless body, it has built-in aid to help you, I don’t think it is a problem. The stop down of the lens aperture to give the proper depth of field is essential, and the Nikon mirrorless viewfinder compensates for the dimness of the stop down of the aperture; you can still see and focus clearly.I used a Viltrox adapter; although it has the electronic interface to the AFS lens, it will not stop down the manual lens aperture; you are stuck with the open aperture, which prevents the use of the better resolution power of the lens by stopping it down, not a very good trade-off.The artistry is good. Adding and removing lenses is smooth and better than Viltrox. The focus is accurate, and the image is sharp as a result. I tried most of my manual lenses; they are compatible.
