In an imaging reader for reading a target located in a range of working distances from the reader, a solid-state imager captures light from the target in the range of working distances over a field of view, an aiming system visually illuminates the symbol with an aiming light pattern, and a steering system steers the aiming light pattern and/or the field of view to be substantially aligned throughout the range of working distances to aid an operator in aiming the imager at the symbol prior to reading.
