PEF

Pentax Electronic File

PEF (PENTAX Electronic File) is a proprietary RAW image format created by Pentax for use in their digital SLR cameras. Introduced along with the Pentax *ist D camera in 2003, PEF contains unprocessed, uncompressed image data directly from the camera sensor. PEF aims to capture the full native pixel depth and color gamut for maximum editing flexibility. PEF files have a 12 or 14-bit depth compared to the 8-bit JPEGs. The .pef file extension denotes images saved in Pentax's RAW format. PEF is based on the baseline TIFF/EP standard with proprietary metadata tags. Third-party software support for PEF has improved over time but still lags behind more popular RAW formats. For Pentax users, PEF provides a specialized RAW option tailored for their equipment and workflow.
