Since EFS lenses only work on cameras with an APS-C sized image sensor, do they take the magnification into account when labeling the mm? What I'm asking is, does a 17-85mm EFS lens shoot at 25.5-127.5mm on a Rebel XSi because of the 1.5x magnification, or is it labeled the mm that it shoots at on the sensor that it is made for?
