I’m able to change focus settings like single focus, continues focus, etc.But then, when I switch to video mode, my camera all of a sudden can’t use the auto focus with this lens anymore. Not able to use autofocus.I bought the adapter to adapt my vintage lenses to my A7iv but also in order to use my 18-35mm Sigma ef Lens for photography.It sits tight, no waggling around or anything and the autofocus works quite fine in photography mode. Sits tight, no wiggling around, got autofocus issues, good build quality. Compatible with Sigma DC 17-70 / 2.8-4 DC OS HSM Sigma DC 30 / 1.4 DC HSM it is not compatible with SIGMA art.
