FotasyAdjustable M42 Lens to Nikkor Z Mount Adapter, M42 Z Mount, fits M42 42mm Screw Mount Helios Lense, Compatible with Nikon Z Mount Mirrorless Camera Z30 Z50 Z5 Z6 Z7 Z6II Z7II z fc Z9

I had purchased a well known name brand adapter ($50+) to couple my SMC Takumar 50mm f/1.4 lens to my Nikon Z8 – wouldn't work properly. To the company's credit they did try via email to help me out but couldn't so it was returned. Took a chance on this "el cheapo" adapter – it fits the Nikon Z camera mount and the M42 thread mount perfectly – and the lens focuses to infinity as it should.More surprisingly, the fit and finish is far superior to the brand name adapter. It has a nice heft to it and looks like it was made by Nikon specifically for the Z8. I was astonished.You can loosen the three adjustment screws with the provided hex wench to align the lens's index mark properly with the camera. This worked well for me but you must be very careful to make sure the wrench is seated properly in the screws' sockets – they are very tiny.

Works great for my Helios adapted onto a Nikon Z8.

Didn't want to spend a bunch for an adaptor to make a cheap vintage lens useable on my digital camera so I did some shopping and this more than meets the mark of adequacy!No fancy packaging and it pretty much takes any M42 lens (vintage Pentax), closes down the aperture and makes it fully useable on a Nikon Z. You won't get autofocus, auto aperture or any contact with the camera so you'll have to create a custom-setting in the menus and tell the camera to fire when there's no lens attached so don't expect magic here!It comes with a hex wrench, too, so you can adjust the rotation of the lens so you make make sure the index marks are at the top, or anywhere else you want them.There are more expense adapters out there and probably none less expensive. Why pay a lot for a peice of aluminum that's little more than a machined tube?

Fits and works perfectly

I am using this adapter as part of a setup for attaching a microscope objective to a Nikon Z camera, and for that it has worked great! I haven’t tried rotating it with the tiny hex key they give you, but for my purposes this thing does everything I expected!

Fits my M42 Takumar 135mm f3.5 lens on my Nikon ZF. I get sharp images and can focus to infinity. Comes with an allen wrench to tighten mount screws if they get loose. Sometimes these screws come loose and people complain that it's a terrible product when all you have to do is tighten the screws. Once tightened I have never seen a loose screw issue on these types of adapters again. If for some crazy reason the screws don't want to to stay tight you can always buy some loctight (something everyone should have on hand) to put on the screw threads that will ensure they never come loose again. But again once tightened I have never seen the issue again. Mine came tight so I have no issues there.

The fit is good.It is not too tight, or loose.The general build quality is very good, for the money.We bought 1, and after reviewing it, we bought 2 more.We found this item to be a good value.

Looks great, works fine. The threads are perfect. No end caps/covers included.
