2003

2011

PEF — Pentax Electronic Format — is Pentax’s proprietary raw format, debuting in 2003 with the *ist D, Pentax’s first DSLR. Like every other major vendor’s raw format, PEF is a TIFF/EP variant with Pentax’s own makernotes storing sensor data, lens info, and shooting parameters. Pentax has always been the quirky underdog — Ricoh acquired Pentax’s imaging business in 2011, but the PEF format carries on through the K-1 Mark II, K-3 Mark III, and every K-series DSLR.

Pentax is one of the few vendors that also encourages use of Adobe DNG — the K-series cameras can write DNG directly instead of PEF if the user prefers archival openness. That dual-format policy (and Ricoh/Pentax’s open-standards philosophy more broadly) is one reason Pentax DSLRs retain a cult following among photographers who value long-term file portability.

MERAK EDİLENLER VE
İLGİNÇ BİLGİLER.

Pentax cameras can write DNG directly as an alternative to PEF — one of the few mainstream vendors that offers the choice.

Ricoh acquired Pentax's imaging division in 2011, bringing PEF into the Ricoh portfolio alongside their own GR series.

The K-1 Mark II's 36 MP PEF files are among the largest raws in consumer DSLRs — typically 45-60 MB.

Pentax K-series bodies have in-body shake reduction — a feature Pentax pioneered before Sony or Canon had it.

Pentax-Ricoh has kept a working DSLR lineup through the mirrorless transition longer than any other vendor.
