Questions & Answers
PEF images: Frequently Asked Questions
What are PEF files?
PEF (Pentax Electronic File) is a raw photo format developed by Pentax as an alternative to the widely used raw formats like CR2 and NEF. It is primarily used in Pentax digital cameras and other devices that support the Pentax system. The PEF raw file format is widely preferred by professional photographers due to its endless editing possibilities. PEF files contain unprocessed images, preserving all the data captured by the camera's sensor, including colour, brightness, exposure, and other settings. As a result, PEF files are much larger in size than JPEG or other compressed formats. The PEF format provides users with more control when it comes to image adjustments compared to compressed formats such as JPEG.
