I have made the mistake on someones word that 669 would fit my 550 holder. Well it doesnt not even close. I actually tried to make it work, it's just to small . Anyway I understand now that it only takes 500 series film like 559 572 552 5 79. But I cant seem to find anyone with that in stock. Where should I look to purchase this film. I live in houston and even houston camera exchange doesnt h ave any, I thought they had everything!

Any help would be appreciated!

still confused,

CK
