I upgraded my A7 Mark II yesterday to firmware 2.0. Tested with Sony 85mm Batis and it worked perfectly. Uncompressed RAW no problem downloading to Lightroom 6. I also updated the firmware for the Metabones IV to version 0.46. Mounted Sigma 24mm f1.4 Art to Metabones IV smart adapter. Attempted to use autofocus in many circumstances: inside and outside, high contrast and low contrast, AF-C and AF-S. I could not achieve autofocus under any circumstances. I switched to manual focus and achieved satisfactory images. Then I switched lenses to a Canon 70-200 f4 L IS lens. Autofocus was perfect and very fast. In fact autofocus was as fast with the Metabones IV/Canon setup as native Sony lenses. I have already notified Metabones of this issue. So for the time being, no autofocus with Sigma Art just manual. Hopefully they can fix this with a future Metabones firmware update.
