I got mine on Amazon: http://amzn.to/2hcxEkl It costs less than $20 and it’s an excellent budget lens adapter made for Sony E-Mount cameras. (NEX series and the A6000/A6300/A6500 mirrorless cameras). They also have adapters available to convert basically any brand of lens to any APS-C, Micro 4/3 cameras you can think of. Check them out here: http://amzn.to/2gi9rMg
I did some quick test with this adapter and some of my Nikon AF-s lens for my Nikon DSLR cameras. All 3 of my Nikon lens performed flawlessly on my A6300 (in manual mode of course). The beauty of this adapter is that it had a build-in aperture ring for 6 full stops of aperture adjustment, so all the lens performed nicely.
For older Nikon F mount lens with aperture ring, you need to set the aperture ring at smallest/locking position and use the adapter’s build-in aperture adjustment. For newer G lens with no aperture ring, just use the build-in aperture adjustment directly on the adapter.
The TTL (through the lens) metering is also achieved and working beautifully with this adapter in Aperture priority mode.
All in all, the Nikon G mount to Sony E-mount lens adapter is a great investment if you have many Nikon lens available at your disposal. They perform flawlessly and the larger aperture available definitely have it’s advantage in creating a shallower DOF and performs better in low-light. Manual focusing with camera’s focusing peak turned on is a breeze and focuses just as fast as autofocus.
