I'm currently trying out the Commlite Nikon AF to Sony adapter on the A7 II. I'm running firmware 03 on the adapter. So far it seems to work quite well with very good single shot and continuous AF. The Sigma Art lenses function almost like a native lens with the adapter. Anyways, I tried the Commlite adapter and Sigma 50mm Art lens out on the streets of LA. Check it out!
