EyeAF Comparison Metabones vs Sigma MC-11 Canon to E-mount Autofocus Adapter
Here's a video by Luis Gabriel Photography showing the EyeAF difference between the Metabones Canon EF/EF-S Lens to Sony E Mount T Smart Adapter vs the Sigma Mount Converter MC-11. The camera used is the newest a7r iii camera controlling a Sigma 135mm f/1.8 Art lens. The video shows how viable it is using Canon EF lenses on the new a7r iii. This makes switching systems easier.
