I am thinking if this could be a possible explanation: The m4/3 use quite a few internal correction to correct the distortion etc, so when we see a 25mm lens, it could be in fact a slightly wider lens such as 23mm, the sensor picks up a wider distorted picture and the body makes some crop and transform and the modified picture is what we see equivalent to 25mm fov. If that's the case, the Dof of 25mm/1.4 would be slightly deeper than the true 50mm/2.8.
