eye focus and face recognition on A7r2 not working

Recommended Posts

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?

yes I think the lens needs to be wide open for it to work consistently and that's a problem when the lighting even on minimum power requires f4.5 or smaller

What lens are you using? My A7r doesn't have any problems on Sony 28 and Batis 85, even when when closed to f7.

makes no difference which lens;  kit lens ,90 macro ,50 mm,  all the same.


it seems to me that you need to be shooting 3/4 or tighter shots for the face recognition or the eye focus to be selected shot after shot

      Raging wild fire in California.  The ashes covers large part of sky, and gives a strange hue.   Sunset in the distance glows in unusual cherry red.  Not a happy day for those who lost their houses 30 miles from where this photo was taken earlier today.  Cross my fingers for those brave firefighters.

      I am trying to set up continuous autofocus without pressing the shutter, and can only get it to work on one of my 4 sony A6000's.  For the life of me I cannot figure out what is different about the settings on that one camera that will enable the lens to refocus without pressing down the shutter when I move the camera around to different subjects.  I have tried different lenses, and they all will continuously autofocus on just that one camera.  All of the sony a6000's have been upgraded to version 3.2.  Thanks for any ideas/help.

      is it just me? I have been trying to use the newish Sony tethered software ,Remote,  but cannot get it to see my A7r2. 
      Tethering works perfectly well with Capture one but all I get is a message telling me to change usb to remote which , obviously , it already is set to.
      the other parts of the software , viewer and edit work ok on already downloaded images 
      The original Sony remote pc software also finds the camera with no issues.
