The emissivity settings have been gone for quite some time, i mentioned it in a previous post. If i had to guess,,,,, the settings were no good so seek just removed them until they can make them work correctly. I think this is one of those "hang in there" moments. I might be crazy here but, it seems like the shutter is operating faster than before the new update. I remember the steady somewhat slow click because i played with the camera for hours. Whatever wizardry has been done in the software has totally removed the gradient from my device and the spot tracking also seems much faster. Cant wait for the next update!!
