FITS WELL TO BOTH CAMERA AND NIKON G LENSES. APERTURE CONTROL ON ADAPTER IS OK.

Attached this to my Sony a6000 and the mount is solid and secure. There were no instructions with the adapter, but going online to forums and reviews for research, I expected that and had no problem getting it to work. I currently have my Nikon 50mm 1.8D lens on my Sony and have had no problems. Manual focusing is a breeze and I have access to all my Nikon glass now.

Contents of the box was the adapter only; wrapped in a small plastic bag. No pouch and no end caps for the adapter openings. I can use the rear lens cap that came with one of my Sony lenses and a body cap from one of my Nikons. Perhaps they envisioned users doing this and saved a few pennies by not providing them with the adapter itself but I would like to have been provided a set with the adapter. Likewise, there were no instructions. (I did not think these two things were worth taking a star away from something that does what it is supposed to do and does it well.)The adapter feels substantial and well-made when you pick it up.It is a simple device – as we know – no electrical connections are made between lens and camera body.It provides a superb and reassuring fit between camera/adapter/lens.Attachment was just as you would want it to be – secure, stable, no wobble in any lateral direction while some slight rotational movement was noted but nothing in excess of what a typical lens-to-body attachment would exhibit.I have tried it with 200 mm macro “D” lens (aperture ring/control on lens barrel) and 14-24 mm zoom “G” lens (no aperture control). Both worked well.“Aperture” control on the adapter had much less travel than I expected but I realized the travel is limited by the travel available within the body of the lens when engaging the aperture control within the lens itself (in the case of the D lenses). I think I was expecting something like focus ring travel but of course it would not be that much. I just hadn’t thought about it before using the adapter.Focus peaking together with Zebra allowed good control of exposure and focus. (I am really loving this focus-peaking thing with my Sony a7ii.)Buttery smooth removal from lens and from the camera body. No trouble as some have reported with attaching or removing the adapter to/from lenses. NOTE: The Release button is NOT a “button” at all; it is actually a lever that you push away from the lens to release the adapter and allow it to be rotated and removed from the lens. I have read comments from several reviewers stating that “no matter how hard they pushed the button” it was exceedingly difficult to remove the adapter from the lens. They just were not doing it correctly.Instructions they SHOULD have provided -When using with a Nikon D-series lens (aperture control ring on the lens itself):• Find the small slide switch ON THE LENS BARREL and make sure it is in the unlocked position (usually toward to the front of the lens) and verify that the aperture ring on the lens can be rotated• Rotate the aperture ring ON THE ADAPTER fully CW when viewed as looking through the camera (might consider using a bit of gaffer’s tape to be sure it doesn't move)• Make your exposure adjustments using the aperture ring ON THE LENS as necessary• If you are using a D-series lens but want to use the aperture adjustment on the adapter then rotate the aperture ring ON THE LENS to its smallest aperture (typically 32 or similar) and slide the lock switch to the locked position.• Make aperture adjustments on the control ring OF THE ADAPTER.When using a Nikon G-series (no manual aperture adjustment control on the lens):• This is easy because the only control you have is the ring on the adapter• Rotate the adapter control ring as needed provide the exposure you want based up other settings you have made• The control ring does NOT move much at all from full open down to smallest apertureWith either type of lens, make your exposure adjustments while looking through the viewfinder or on the monitor. Use of focus-peaking is very helpful for optimizing the focus which, of course, is manually adjusted when using one of these adapters with Nikon lenses. Turning on the Zebra function (first setting under the “gear wheel” in the Menus) is also VERY helpful to control exposure.

Après quelques jours passés avec cette bague adaptatrice répond à mes attentes, la construction et finition sont bonnes.La bague de contrôle du diaph a par contre une course assez courte, mais vu le prix on s'en contentera très bien.

Reglage de diapraphme est tres difficileSur Nikon 300/4 les images ne sont pas nette et il y a beacoup de "purple fringing "
