Bedeviled by the A77 preview button
Ok, so I'm familiar with the preview button on the A700, showing me the DOF, however I can't seem to get my head around the preview button on the A77.
After I receive focus confirmation (or peaking in manual focusing), I push the Preview button, however something weird happens, the focus point becomes blurred and other areas come into focus, if I take the shot, my original focus point is indeed in focus.
So what am I missing here??
