>>2715089Ricoh bought out Pentax, not the other way around.
And the oldest GR's said "Pentax Ricoh" as the company name in the exif, because that acquisition occurred before it came out.
Later, Ricoh decided to change the merged company name to just Ricoh, so later cameras just said "Ricoh" as the company name in exif.
Of course if you upgrade your firmware, that updates as well.
