The Commlite lens mount adapter is the first lens adapter that allows you to retain Autofocus (AF) capability when connecting Nikon Lenses to Sony E-Mount cameras, including the A6000 and A7 series cameras.
The adapter allows for Contrast Detect AF (slow but accurate) on most E-Mount cameras but supports quick Phase Detection (PDAF) for the A7II and A7RII cameras. Note: A7II owners will need to upgrade to Firmware version 2.0 to access PDAF.
It is designed with a built-in Clickless Aperture dial that comes with 16 exact stops and detachable 1/4 Tripod foot.
My recommendation is that unless you own the A7II or A7RII cameras and can access the PDAF, I would save yourself a few hundred dollars and stick to a Commlite Manual AF adapter or put the money towards a high quality Manual-AF Novoflex adapter as the Focus Peaking and Magnify View features make for accurate manual focusing on Sony Alpha Cameras.
