Despite being a brand-new camera, the Pentax 17 borrows many legacy details from past Pentax cameras to inform its distinct design: the film rewind knob is taken from the Pentax LX, the ISO dial from the SP, the flash and shutter release from the KP, the lens housing from the Espio Mini, the front logo text from the 67, the knurled battery cover from the DA WR series of lenses, the film advance lever from the Auto 110, and the magnesium alloy top plate from a special edition LX. Also, the viewfinder includes Pentax's own classic logo along with the Asahi AOCo logo and a film plane indicator taken from their line of DSLRs.
