IMPLEMENTATION

Viewers responsible for this format

PEF is Pentax's proprietary RAW format for sensor samples and camera metadata. Anyfile extracts supported EXIF and maker information, uses an embedded preview when available and attempts a LibRaw development.

Common question

Is PEF interchangeable with DNG from a Pentax camera?

No. Both may represent the same capture intent, but their containers and metadata organization differ.
