When the AUTO KNEE function is activated in a situation like this, the background can be reproduced distinctly. This function is very effective for shooting in the following situations.

OWhen shooting people in the shade under a clear sky OWhen shooting people inside a vehicle or a building and

outdoor scenery seen through windows at the same time OWhen shooting scenes with a high contrast
