The magnification of the SX series depends on the configurationof the system. The available magnification is a factor of the objective, the internal optics and the selected eyepieces. The maximum magnification for each of the SX series models is: SX25 Elite = 5x – 180x, SX45 Elite = 4x – 200x, SX80 = 4x – 256x, SX100 = 4x – 320x
