Pentax PEF (or Pentax RAW) is a raw image format associated with Pentax digital cameras. It is based on TIFF.

Identification

If, in the first TIFF IFD, the Make or Model tag has a value that begins with "PENTAX", or the Compression code is 65535, it's probably a PEF file. The MakerNote values for most Pentax PEF files begin with the ASCII "AOC MM".
