Great news! After a very long wait I got my Commlite Nikon F to Sony E Adapter today. I will put the adapter through its paces this weekend on a Sony A7 Mark II with my three Tamron Lenses: 15-30 F2.8, 24-70 F2.8 and 150-600 F5-6.3. So stay tuned for a full review!
My first impression of the adapter iteslf is very good. It is made out of metal, the inner barrel is matte so there will be no reflections on the picture. It feels very solid and attachted to the lens nothing rattles. The fit is very tight so hopefully there will be no light leaks.
Here you see 3 first images of the adapter:
