DX Coding......Medium Format??? Hi, I am a currently studying photography and have been given a research assignment on medium format cameras. My question is ... Can medium format film be DX coded? If no, why not? and if yes How? I have pretty much figured that DX coding is used for the newer and more advanced 35 mm cameras but I have not been able to answer the why not part of the question. Any help on the subject will be greatly appreciated. Kind Regards, Augusta

To answer if it can, I would think that it can because the dx code on 35mm is the grocery store looking bar codes on the film cartridge, and the camera has something to read that. So I would say that it's possible that medium format can be dx coded. Whether or not any of them are is another question.

While the DX coding looks like supermarket bar code, it is different. Bar codes are scanned optically, while the DX code metallic and is read electronically with contacts in the camera. The DX code can be applied simply and cheaply to the film cartridge. Medium format roll film is not loaded into cartridges. It is not economical nor practical to add a metallic film stip for DX coding to the back side of 120/220 film.
