cheers.
Pretty sure that as EFS lenses are designed only for APS-C sensors the focal length quoted is what you get with that sized sensor and there is no crop factor multiple.

For example at 55mm on either the 18-55 EFS or the 55-250 EFS that would be the same as me setting my EF 24-105L to 55mm on my full frame 5DmkII.
