Or maybe

When the metal backfocus is quoted as 44mm, is it referring to where the image comes to focus behind the mounting surface of the lens OR is it referring to the position of the senor inside the camera body (44mm below the camera mounting surface?) If its the later, this could explain it, because there are filters inside a camera that will increase the length of the optical path, which may not be the case so much with your ASI camera. just some thoughts ...
