Increasing Depth of Field (Focus Stacking)

Combine multiple images for a depth of field greater than can be obtained with a single shot. The camera takes a series of shots at focus distances both in front of and behind the current focus position and creates a single image from the areas that are in focus in each shot.

Choose this option if you want all areas of the subject in focus in photographs taken at short ranges or wide apertures (low f-numbers). The pictures are taken in silent mode using the electronic shutter.

  • The composite image is recorded in JPEG format, regardless of the option selected for image quality.
  • The composite image is enlarged 7% horizontally and vertically.
  • Shooting will end if focus or zoom is adjusted after the shutter button has been pressed all the way down to start focus stacking photography.
  • If focus stacking fails, the camera will record the selected number of photos without creating a composite image.
  • This option is available only with lenses that support focus stacking. See our website for information on compatible lenses.
  • Pictures taken with an art filter selected for picture mode are recorded in [Natural] mode.
