Yesterday I had a newborn photoshoot, it was my first with my new a7iii, for lens I chose the 24-70 GM
I opted for using AF Single with Flexible Spot small to place the focus where I wanted it, sometimes it would be on the feet, hands, fingers, eyes....
The photoshoot started and the camera seemed to focus well with no problems, after a while it would not focus at all in the eyes area, it would hunt but it would not lock focus at all, it was very frustrating.
In the room there was enough light from my strobe modelling lights and the ambient light, I was using mechanical shutter with Live Preview Off, Eye AF off too and no Face detect, just placing the focus on the eye and it would not focus at all.
Not sure if had anything to do, but as the baby was naked we had a heater on and the studio room got quite hot.
Any ideas on what I might have been doing wrong? Or was it the camera?...I want to think it was me and not the camera
