we could just as well call it 0.6x crop factor if you were used to a 6x6 hasseblad camera where you'd consider 80mm normal
small mistake in numbers here, compared to a 6x6, the 7D would have a crop factor of around 2.5x. but the point was that whenever you use the crop factor term, you'd have to define *what* it's compared to to make sense. so while it might make it easier for people who only used one format before (like, photographers going from 135mm film to APS sized sensor digital cameras), it's very confusing for all those who use multiple formats (16mm? super16mm? 35 academy? alexa? cinemascope? etc). so it's best to just state the *true* (ie optical correct) focal length and the sensor/film size that you used to record the image.
sorry for drifting off-topic... as nathan said, the short story is just use the correct focal length and the correct film back ;)
