However, the MX was designed as the mechanical twin sister of the remarkably successful entry-level Pentax ME.

The MX is all manual: it does not feature autofocus or autoexposure modes such as aperture-priority, shutter-speed priority, or full program.

Due to its complete lack of automatic functions, but excellent array of manual controls, the MX is often selected as a camera for photography students to practice their technique.

The depth-of-field preview and self-timer functions render the MX superior in this respect to the earlier and less expensive Pentax K1000.
