What is new ? (4)
Vivid, sharp and crisp images obtained at the
default settings.
Previously, images shot with EOS-1D series camera's default settings
were of without sharpness applied and the colors were less saturated.
Therefore the users often misunderstood that the images of EOS-1D
series were soft and not in focus.
The default setting is "Standard" with vivid colors and sharpness applied.
