Legend:

  • 1 – Image circle not sufficient or borders with vignetting or optical aberrations
  • 2 – K10D can be updated to change from Powerzoom-use to SDM-drive.
  • AF – Screw drive autofocus
  • Av – Aperture priority
  • Av0 – Aperture priority only with open aperture
  • M – manual exposure with exposure display
  • M+ – manual exposure with automatic working aperture metering, no exposure display
  • P – Program AE
  • PLM - Autofocus with pulse motor
  • PZ – Powerzoom (K10D with limited capatibility only)
  • SDM/DC – Autofocus with supersonic- or direct current motor (K10D with firmware version 1.3)
  • Tv – Time priority
  • X – not useful, because smallest aperture always set

Comments:

  • On cameras with KAF/KAF2-mount without aperture simulator during Av metering the aperture has to be adjusted on the camera.
