DOF (Depth of Field) question CYCLES

Hi,
When you are creating a depth of field effect in cycles, you can do so plainly by configuring your camera. You can also add a defocus node in the compositor to configure the result. I wonder why would you want to set a defocus value in the camera settings, when you can simply just enter where you want the focus to be, and then play around with the settings in the compositor? As it’s hard to get the right settings right away anyways. Is there any difference depending on how you do it?

Thanks,

Oh, thanks! Very well explained with the example images too! :slight_smile:
