Shooting with the Olympus E-M1 Mark III, I rely pretty heavily on Face Detect AF in general, but needless to say there are cases where it fails and the camera will fall back to using single point focus. Sometimes this can come in the middle of a shot sequence and in a performance photography context this can result in wildly different exposures since the camera's metering will change if a face is detected. I'm pretty "active" in using Auto Exposure Compensation, but that can also exacerbate matters when the Face is no longer part of the equation.
Anyone else encounter this issue and found a workaround? Keep in mind that this is in the context of performance photography, where conditions are changing constantly and the dynamic range tends to be pretty extreme. Example, below...
