I currently have a Commlite AF adapter with a Sigma 50mm f/1.4 Art lens mounted on my Sony A7. The lens racks from end to end when I turn on the camera OR when I toggle the AF/MF switch on the lens barrel. However, it doesn't autofocus with a half-pressed shutter. Question: Is the adapter plug and play or is there some in camera settings that I have to adjust to have the adapter play nicely with the body? Zeiss sent us a Loxia 50mm f/2, so I am doing a comparison test of the Loxia 50mm f2, Zeiss/Sony 55mm f/1.8, and I was hoping to include the Sigma 50mm f/1.4 Art (since it is one of the best 50mm on the market today). Was hoping to get the AF to work. Unfortunately, it seems Focus Peaking or Focus Magnification is not available with the adapter either! Weird.
