Hi on Saturday , not for the first time, I gave up trying to use the eye focus on my A7r2.
It matters not which lens I have fitted, but the acquisition of a face square and the eye focus square are random to say the least.
Given the praises that have been sung over these focusing aids I have to assume I have something not set correctly.
I was taking 20-30 images of 50 models at speed so I tried both continuous and single focus modes, full focus area and zone are and even centre area. I have face recognition turned on and eye focus assigned to c3 button.
I was shooting with studio lights at f8 _ 1/160 _ iso 100 all day .
Is there a focal length that works better, I see videos of people using all sorts of focal lengths and still saying how brilliant the eye focus is.
I found standing in roughly the same place and the models the same that the face recognition was totally random when it appeared. The images them selves are fine , in fact every one is in focus so thats not a issue.
What are the aperture and other parameters that you have found that allow the camera to regularly find faces never mind the eye focus?
