There is set forth herein an imaging terminal having an image sensor array and a variable lens assembly for focusing an image onto the image sensor array. In one embodiment, an imaging terminal can include one or more focusing configuration selected from the group comprising a full set focusing configuration, a truncated set focusing configuration and a fixed focusing configuration. When a full set focusing configuration is active, a full set of candidate focus settings can be active when the imaging terminal determines a focus setting of the terminal responsively to a trigger signal activation. When a truncated set focusing configuration is active, a truncated range of candidate focus settings can be active when the imaging terminal determines a focus setting of the terminal responsively to a trigger signal activation. When a fixed focusing configuration is active, the focus setting of the imaging lens assembly can be fixed so that a predetermined lens assembly focus setting is active when a trigger signal is active.
