Pentax Electronic File



PEF is a digital image format used in Pentax digital cameras. Like NEF, CR2, ORF and other raw formats, PEF has all functions of a digital negative. Raw formats are referred to as digital negatives for the simple reason that they fulfill functions equivalent to those of analogous film negatives. They just contain all the data that normally makes a photo image.


*.pef file type is supported by this model:

  • Pentax istDS
  • Pentax istD
  • Pentax istDL
  • Pentax K100D
  • Pentax K10D
