Morphology

prefocus = focus (transparent) = pre + focus

The meaning is a straightforward application of the productive prefix 'pre-' to the verb 'focus', meaning to focus beforehand.

Etymology

Prefocus combines pre- ('before') and focus ('make sharp'), so to prefocus is to set the camera's focus 'before' the moment happens, making you ready to take the picture.
