Sorry to barge in with a question but can I ask people what their settings are for portraits on the A7iii? I've been mainly using Eye-AF or at least AF-ON to focus when in general but today the AF-ON button was completely unresponsive (either in AF-A or AF-C) using the Samyang 50mm (autofocus version). I even tried manual focus which didn't seem a lot better. I switched to my other lens (also Samyang, but the 35mm f/2.8) and straight away it was focusing without a problem, which makes me think it's the lens as I've had more problems using it with shots in focus.
But not being a regular photographer and being new to Sony I'm worried it might be user error. I've watched a few videos on YouTube of various people going through their settings so I'm not doing anything too crazy or wrong I think (and I am keeping my Eye-AF or AF-ON pressed down when pressing the shutter-release which I hadn't been doing before) but sometimes it won't let me take the photo (even though I have it set up for 'Balanced Emphasis) since the focus didn't move at all.
Is it the lens or is something off with the camera? Or is it me
