A very non-scientific review of my new Metabones Smart Adapter MKIII. My comments are in Norwegian, but I have titles describing what you see and what I have tested.
I have done a simple test in my backyard with Samyang 85mm f/1.4, Sigma 18-35 f/1.8, Canon 70-200 f/4 and Sigma 20mm f/1.8.
I used a monopod and not i tripod which you can see in some of the scenes. The camera is a Sony ILCE-6000.
