Works with all Nikon manual lenses.

Very useful for using my old Nikon manual targets (no autofocus) on my Canon EOS RP. Great results, no appreciable bias for missed alignments. Bayonet insertion with the right tolerance, neither too tightened nor too much leasure. You get great performance with manual focus.

When I ditched my Nikon and switched to the Sony A7IV, I chose this adapter because of the amount of Nikon lenses I already had. Primarily for my Nikon macro lens, on which I focused manually most of the time anyway, it doesn't bother me at all that the adapter is manual. Money was clearly saved here by saving myself the Sony macro. The adapter sits well on the camera and lens, so it fits extremely well and looks sleek. A Nikon lens on a Sony body is always an eye-catcher. The aperture ring is of course also manual and does not tell the camera what aperture level you are at. In the metadata of the photos, it simply shows F--. So you have to develop a feeling for which aperture you have just set. I did notice a little more Cromatic abortion, but that can be quickly remedied in Lightroom by selecting the lens. Images are sharp and the adapter has no downsides other than adding some length to the lens.

I used it to combine old manual Nikkor lenses with the Nikon Zii. Obviously the operation of the device is manual only with some difficulty in focusing as the mirrorless device doesn't have a colored ball to indicate when focus is perfect, unlike the digital device like the D810.

For Camera & Laser Level

Camera lenses can be expensive, especially when they combine both their ability to be fast in terms of aperture and being a prime, but this one goes against the grain as it's fairly inexpensive for what it is. The lens is made by Yongnuo, a Chinese company that manufactures camera accessories. ====== Construction ====== The lens is a stubby lens, a similar size to a Nikon 50mm with only one focus ring and an auto/manual switch. There's no manual opening ring on this one, so it's pretty easy to set up. I wouldn't say it's as heavy as my other lenses, but it appears to be constructed of similar materials. The lens came in a box with plastic covers statically attached to each glass end so it was protected right up to my door which is a nice touch. ====== Usage ====== I use this lens on my D800 and I've had great results so far, having an F2.0 aperture can certainly help bring those slightly wider shots into depth of field. I've used the auto and manual focus features and found it to be responsive and accurate. I found the sharpness to be good — it's not as good as my Nikkon 50mm, but it's close enough for the effect I want. That's not to say the image isn't sharp, it's just not as razor sharp as I've seen from some other lenses. It will certainly bring some sharpening in post again. ====== Conclusion ====== This is a great lens for those who don't have the money to splash out on a Nikon branded lens, but the results are still good. I would recommend this to any photographer and I will buy from Yongnuo again.
