PEN images: Frequently Asked Questions
What are PEN files?
The PEN photo format from Pentax refers to an obsolete image file format that was used primarily in the company's earlier digital cameras. This format was designed to support digital photography but has since been rendered outdated due to advances in technology and the rise of more versatile and efficient formats, such as PEF and DNG. As a result, PEN files are rarely used today and are often incompatible with modern editing software and workflows. Collectors and enthusiasts of vintage photography may still encounter this format, but it lacks the widespread support and utility found in contemporary file types.
