Fotodiox Pro Lens Mount Adapter - M42 Type 1 Screw Mount SLR Lens to Nikon F Mount SLR Camera Body

I like the quality of this brand, don't have any complaints.

I like this product, it seems to be well made, the lenses I have (Pentax mount or M42) fit the adapter well, the adapter fits my Nikon D3300 just fine, and the vendor's delivery was great. However (and this is a big however) the adapter will NOT work on any lens that has Automatic aperture - you can tell if your lens is automatic by looking at the bottom of the lens (where it screws into the camera body) and locating a spring loaded pin. If your lens has an automatic aperture, there is no facility for the adapter to force the lens into manual mode hence the only aperture available is full aperture, i.e. 22. That means that lighting is off and focus in dark light is off and basically all the lenses I have cannot be used with this adapter. That doesn't mean I rate the adapter poorly, after all it is doing what it is advertised to do. I simply have no manual aperture lenses hence I cannot use any of my M42 mount lenses on my Nikon D3300. Disappointing as that may be. Remember too that the adapter is not made to support auto-focus so you will have to manually focus the lens, which did not enter into this review since I figured that out before I ordered it. The reason I rated Picture Quality and Auto Focus low is that I could not get the aperture setting correct nor could I get auto-focus. That does not mean the adapter is bad, it simply is not made to support either feature. If you have a fully manual lens (aperture and focus) this adapter will work fine - hence the 4 star review. If you (like me) want the aperture support with manual setting of aperture and focus plus the ability to have infinity focus (this adapter doesn't support infinity focus) then I suggest looking at the Vendor's website for the Fotodiox Pro Lens Mount Adapter - M42 Screw Mount SLR Lens to Nikon F Mount SLR Camera Body with Infinity Focus Glass. A bit more money, but worth the added cost for total support of your vintage lenses. Update: I received the M42 to Nikon F adapter with infinity focus today and am glad to say it works perfectly. I am now able to use the lenses from my older film camera (Mamiya/Sekor) with my Nikon D3300. Still manual focus and manual aperture, but that's not a problem.

Works as advertised. Purchased for my Nikon D3500.

I have vintage 50 and 58 mm M42 lenses and bought this to get them onto my Nikon D200 and D300 cameras. When doing so, I can NOT get the lenses to focus. Anyone else having this issue? It's more trouble than it's worth to return it so I'll just keep it.

infinity focus was not possible.

The adapter makes the lens fit on the camera, but the geometry is all off, and the result is that it will only focus to about 6 feet (2 meters) away from the camera, and everything else is out of focus.

Don't waste your money on the m42 to F mount adapter. They machined it incorrectly to line up so you have infinity focus on nikon bodies. I had a d7000 mounting a 28mm takumar m42. No dice.

It was very difficult to get it to lock into my place. When it tried to remove it from the camera, it didn’t want to come off. It took me about half an hour to get it off. I was afraid it might have damaged my camera’s mount and contacts.

I'm sure this works just fine. Not impressed with postage. Incredibly slow.

I had ordered a much expensiver item a few weeks ago but was unable to bring my Tessar 50mm f2.8 to infinity (due to the presence of a lens; So, after searching internet and asking advice on a FB group, I ordered this item. It's got an excellent finish and is very disreet on my D800/D850 ... but most important my Tessar goes to the ... finish.

Bom adaptador, cumpre a função.

Serve it’s purpose as supposed!

Me gustó mucho hace muy fácil usar mis lentes análogos y encaja a la perfección con mi nikon que tenia guardados de verdad muy buen producto lo recomiendo al 100 y
