DrawEngines: Depth Of Field Units
The unit system is designed for displaying and editing and not for
rendering. Eevee, Workbench and GPencil used these settings to convert
the focal length and sensor size to world units. Making depth of field
render differently with Cycles.
For now we will remove the scale in the draw engines to match cycles,
until we implemented a camera parameters specific scale.
