Each rover will carry two cameras: one that is for showing large panoramic views of the Martian terrain and one that will zoom in on the interior structure of rocks.

Panoramic Camera (Pancam), a high-resolution stereo color panoramic imager, will reveal the topography, structure, mineralogy, and texture of the scene around the rover at resolutions three time higher than any other Mars surface camera. The detectors are 1024 x 1024 CCDs. The camera has 14 color filters covering the spectral region from 400 to 1100 nanometers. Narrow-angle optics provide an angular resolution of 0.28 milliradians per pixel.

Microscopic Imager (MI), like a geologist's hand lens, is for close-up imaging of rocks to see their texture and structure. Compositional data is obtained by other instruments. Its spatial resolution is 30 millimeters per pixel over a 6-millimeter depth of field. Its CCD detectors and electronics are identical to those on the Pancam.
