Talk:Pentax PEF

Have we been able to verify the .PTX extension for Pentax RAW? Can't find any documentation. --Thorsted (talk) 23:24, 8 November 2019 (UTC)
 * I don't know where .ptx came from, but it probably wasn't from anything authoritative. I can find hints that .ptx works as an alternate extension . I don't care if we de-list it, or leave it. -Jsummers (talk) 17:24, 9 November 2019 (UTC)
