The X-5 features the PENTAX-original Auto Picture mode, which automatically assesses the subject's conditions and selects the most appropriate shooting mode from 16 distinctive shooting options, including Landscape, Portrait, Candlelight and Pet.
The programmers who created the original AutEx system, which ran on two huge Xerox Sigma 9 mainframes in lockstep mode (either one could take over if the other went down), have long since retired.
