Thank you for that. First time I heard of Minolta Celtic. Of course, that would only be for a Minolta branded lens, with a Minolta mount. The OP has also mentioned Star D and Vivitar MC. For Vivitar, MC means multi-coated. The Vivitar multiplier is for a Pentax K bayonet mount. Hopefully the links I provided will enable the OP to determine which mounts he has, so he can select the correct adapter. Thus far, we do not know which adapter he has. Again, thanks for the education on Minolta Celtic.
.... Yeah, l didn't think beyond the Minolta! Too early to think, I guess!! You are correct!! The Vivitar would have it's own nomenclature.
