- I've seen quoted in a number of publications that the
- Canon EOS 100 (Elan) looks at the DX-coded number of
- exposures on the film canister and will rewind when
- this number is reached. However, if you look at the DX
- contacts in the film chamber you will see that there
- are only 6 : one earth and the 5 bits of DX-coded film
- speed. There are no contacts on the second column of DX
- information (which includes the number of exposures and
- the film exposure latitude in stops) therefore the
- camera cannot see this information. I would maintain
- that the EOS 100 will not wind beyond 36 because this
- is the (usual) maximum number of frames in a 35mm
- canister and not because it reads the DX-coded
- information.

- My EOS 1000 (Rebel) (which also has only six contacts) seems to wind
- the film all the way; this usually gives 37 exposures on a 36 exposure
- roll.
