a77 af area disappear
A couple of times, the af area squares in the viewfinder disappear after taking several shots. Has this happened to anyone else?
Are you sure you did not press the Disp button by accident?
More seriously, I haven't noticed it, but I suppose it is possible that the AF area outlines disappear briefly, just for a split second.
What is the problem? How long do they disappear for on your camera?
