- As a single data point, I can state that a lot of times I have managed to
- get a 25th frame out of a 24-exposure film without ever tearing the film.
- My camera is a 630.
-
- Besides I can hypothesize that the Elan/100 will not allow shooting past
- the 36th frame although its motor is weaker that the one in the 630/RT/10s.

- One disadvantage of the RT that I feel should be mentioned is that
- the user cannot clean the mirror. If it gets dirty, you send it to
- Canon. Therefore, lens changes on dusty environments are not advised.
