1. An imaging reader comprising:
an image sensor configured to receive an image of a target and to generate an image frame representative of the image of the target;
an optical assembly configured to form the image of the target on the image sensor;
a distance determining module configured to determine a distance to the target;
an autofocus component configured to implement the distance determining module;
an indication determining module configured to determine an out-of-range indication when the distance satisfies a first condition;
an indicator configured to present the out-of-range indication, the out-of-range indication being a varying out-of-range indication that varies based on the distance;
wherein the image sensor is configured to capture a representation of the image of the target when the distance satisfies a second condition;
an indicia decoder configured to decode an indicia in the representation to determine an indicia payload; and
a communication interface to convey the indicia payload to a host system.
