Mark II Posted March 1, 2019 Share #1 Posted March 1, 2019 Advertisement (gone after registration) Before I destroy a couple of rolls when shooting, does anyone know if the optical DX code reader in the M7 will cause problems with SFX200 (or any other IR sensitive) film?

pico Posted March 1, 2019 Share #2 Posted March 1, 2019 When in doubt of the DX reader, set the ISO manually using the dial on the back. Link to post Share on other sites More sharing options...
Michael Geschlecht Posted March 1, 2019 Share #3 Posted March 1, 2019 Hello Mark, Are you asking whether or not the Optical Reading Device will effect the film when it is reading the information on those little boxes on the side of the film cartridge? Best Regards, Michael Link to post Share on other sites More sharing options...

Best Regards, Michael I think the question pertains to if the ORD will pick up the right DX information to set the right ISO to meter with. Link to post Share on other sites More sharing options...

I don't think so. I think the OP is asking whether the optical DX reading diodes (or wherever they are called) will emit IR and fog the film. Link to post Share on other sites More sharing options...
wattsy Posted March 2, 2019 Share #6 Posted March 2, 2019 A quick google on the subject seems to result in mostly speculative opinion that the optical DX reader will probably fog IR film. Ken Rockwell says it definitely will so therefore it must be true. 😀 Link to post Share on other sites More sharing options...
Mark II Posted March 3, 2019 Author Share #7 Posted March 3, 2019 Advertisement (gone after registration) I always set the ISO manually, so the film speed should be fine. The worry is if the IR LEDs in the DX reader will cause any fogging - I could not find a definitive answer via google, but I am sure someone must have used this film in an M7!
