A7rii Tamron SP 150-600mm LA-EA4 Video Autofocus Performance
Sony A7rii with Tamron SP 150-600mm adapted using the Sony LA-EA4. This lens seems to work far better with the LA-EA4 across all of the Sony E mount cameras than the LA-EA3. I found video autofocus to be very acceptable and continuous flexible spot focusing very acceptable for photo taking.
