John Saves Posted January 3, 2016 Share #1 Posted January 3, 2016 Advertisement (gone after registration) hello, i accidently left the iso-setting of my leica m7 at "dx" while shooting a non-dx film (Bergger BRF400+, iso 400). According to the manual the m7 should use iso100 if the dx information of the film is not recognized by the camera. The weird thing is, that the viewfinder shows "5000" when switching the camera on. Does it mean that the non-dx Film was recognized wrong as iso 5000 film - and the film was way underexposed? Or is the film still exposed as iso100 Film as the manual concludes?

pico Posted January 3, 2016 Share #2 Posted January 3, 2016 I think that is an error message beginning with S. Link to post Share on other sites More sharing options...
John Saves Posted January 5, 2016 Author Share #3 Posted January 5, 2016 Ok - thank you! I'll develop the film like a iso100 film and pull it by one f-stop! Link to post Share on other sites More sharing options...
Michael Geschlecht Posted January 5, 2016 Share #4 Posted January 5, 2016 Hello John, Welcome to the Forum. An ISO of 5000 means that your film cartridge had a surface that was read at that number. Normally the film speed section line of all 12 of those little squares on 2 lines on the cartridge are a mix of white & black. Numbers 1 & 7 always being white. As I remember (I am away from my reference materials at the moment) an entirely white surface reads as ISO 5000. Best Regards Michael Link to post Share on other sites More sharing options...
John Saves Posted January 6, 2016 Author Share #5 Posted January 6, 2016 Thank you! The colour of the film cartridge is actually light grey - so it could be possible, that the dx reader read it as iso 5000... :-( I think i'll develop only a few slides of the film to see how it was actually exposed.

wattsy Posted January 6, 2016 Share #6 Posted January 6, 2016 I think i'll develop only a few slides of the film to see how it was actually exposed. Yes, a clip test may be the best answer. If you have exposed as if the film was ISO 5000 you would presumably have seen much faster shutter speeds than you might otherwise have expected for the given light conditions?

Actually yes - i remember wondering about fast shutter speeds... Link to post Share on other sites More sharing options...
wattsy Posted January 6, 2016 Share #8 Posted January 6, 2016 Actually yes - i remember wondering about fast shutter speeds... I think it's reasonable to conclude you did expose at ISO 5000 and will need to push the film in development (4-5 stops ). Link to post Share on other sites More sharing options...
