Systems and techniques relating to a microscope with an adjustable stage are described. A microscope includes a base, a support arm attached to and extending upwardly from the base, a head attached to the support arm, the head including a lens, and an eyepiece attached to the head. A stage is releasably attachable to the support arm between the head and the base at multiple locations, providing multiple working distances between a lower surface of the head and an upper surface of the stage. When the stage is attached to the support arm at a location, a working distance between the lower surface of the head and the upper surface of the stage is further adjustable to an either greater or lesser working distance. In another embodiment, microscopic and macroscopic viewing can both be provided using a lens changer with multiple lens positioned radially about an axis of rotation.
