John Salim Posted July 2, 2023 Share Posted July 2, 2023 Is there a definitive guide for the notch coding on a 'Single 8' cassette ? I see there's three possible areas on a cassette for switching ( see photo ) Many thanks all, John S ? Link to comment Share on other sites More sharing options...
Premium Member Simon Wyss Posted July 2, 2023 Premium Member Share Posted July 2, 2023 There is ISO 3646 that defines everything about the cassette. Film speed is represented by 4-degrees steps from 22 through 78. 1 Link to comment Share on other sites More sharing options...
Joerg Polzfusz Posted July 2, 2023 Share Posted July 2, 2023 There are three alternative places that define the speed. Most cameras made/sold by Fuji are using the „arc“ (1). An exception is the AX100 (which was made by Kokah and only distributed by Fuji). But I don’t remember whether it’s using the holes (2) or the position of the „nose“ (3). Not sure about the C100. The Elmos are all not using the arc. Same is true for the first Canon. Not sure about the second Canon, the Konicas and the Yashicas. Beside the tungsten/daylight notch (that AFAIK is not used by any camera), Fuji also added „some more holes“. Their purpose is unknown to me. Some say that Fuji used them to automatically differ between Fujicolor (K-12 process), Fujichrome (modified E6) and Fujipan/Neopan (b&w). But I cannot tell whether this is correct. Hope this helps Jörg 1 Link to comment Share on other sites More sharing options...
Joerg Polzfusz Posted July 3, 2023 Share Posted July 3, 2023 (edited) BTW: Here‘s an interesting Japanese article on the three means of indicating the film speed (with Google translation): https://www-muddyfilm-net.translate.goog/2006/04/single8speedset.html?_x_tr_sch=http&_x_tr_sl=auto&_x_tr_tl=de&_x_tr_hl=de According to that page, the „lower notch“ isn’t to distinguish between tungsten and daylight balanced films, but between b&w (notch filled = not present) and Fujichrome (notch present). Strange… Edited July 3, 2023 by Joerg Polzfusz Link to comment Share on other sites More sharing options...
Joerg Polzfusz Posted July 3, 2023 Share Posted July 3, 2023 On Muddy‘s webpage, you can also see one of those „additional holes“ that are present on the cartridges of the Fujichrome RT200N, but not on the other cartridges… Link to comment Share on other sites More sharing options...
John Salim Posted July 3, 2023 Author Share Posted July 3, 2023 Thank you Simon and Jöerg for your help and very useful information. It will be useful as future reference when reloading ( unknown ) cassettes with regular super 8mm stocks. Best wishes, John S Link to comment Share on other sites More sharing options...
