After you've bought that relic how do you use it when the film size is no longer made?

Two US sources carry many discontinued film sizes. Chicago retailer Central Camera sells fresh rolls of film in sizes that are no longer available elsewhere. Click on "Impossible to Find Items" on the home page. On the second page click on "127, 620 and Other Exotic Film Sizes." Prices are listed and Central Camera provides a toll free number for orders.

Since 1988, Film For Classics has been selling fresh black and white roll film for antique and classic cameras, including 127, 620 and 828 roll film. 127 and 620 film comes in color print, color slide and black and white. 828 film is available in color print film only. Hand spooled Kodak Plus-X is offered in these film sizes: 101, 103, 116, 122, 124 and 616. Processing is also available. Order by mail.

Hint: Veteran photographers know the only difference between 620 and 120 film is the spool the film is wound on. To save money, buy a few rolls of 620, save the spools and start rolling your own (in a darkroom, of course!) This is not quite as simple as it sounds. Wear cotton gloves and work in a clean environment. Attach the end of the 120 film to the paper backing with masking tape before you start respooling the film and paper backing on the 620 spool. You may need to adjust the piece of tape which holds the film to the paper backing at the start of the roll.

Some people protect the 120 film by rolling it onto an empty spool (either size) then rerolling it onto a 620 spool.
