I have several 126 Cartridges of Kodacolor Gold, ASA 200, that expired in 1996. I have heard that Kodacolor Gold holds up pretty well so I was anxious to shoot a roll. I loaded it into a Minolta Autopak 700, closed the back door and the exposure needle which was working a few seconds earlier, refused to react to the light. So I took it out and put in an empty cartridge and the exposure needle worked fine. In comparing the two cartridges I noticed that the "fresh" cartridge, (the 1996 cartridge), did not have a notch at all. This is the first cartridge I have come across with no film speed notches at all. So I cut a notch in the frame of the cartridge in the same position as another, older, Kodacolor Gold 200 using an X-acto knife, put the cartridge back in the camera, and the exposure needle worked fine. So I guess for that particular camera at least the notches are necessary for the automatic exposure and or the metering to work. I have several empty cartridges notched for speeds of 64, 100, 125, and 200 and each one gives a different reading on the Minolta's meter so the notches must be somewhat important. When I load 35mm film a 126 cartridge, I try to match the film speed to a matching cartridge. I don't have a 400 cartridge so if I shoot with ASA 400 film I will put it into a 200 cartridge and change the f stop manually. Has anyone else run across the 126 cartridges with no notches? Thanks!
