I've always wondered about those Celtic-badged lenses. Being a "Mick" and having grown up in the Larry Bird era in Boston, Celtic is a word that jumps out at me, but I don't associate it in any way with Japan. Seems like an odd choice of name on Minolta's part. But, mostly, I've wondered why they had the separate line, and if it was their budget line. It seems to perform well, though.
