Well, this is just a guess but the 18-55 only fits one camera -- the

300D. If you consider the 1.6x focal length multiplier, the 18 mm wide

end becomes 28.8 mm. The specs for the EF 28-200 are no doubt given

based on its actual widest focal length of 28 mm. Therefore, the angle

of view for both lenses would be the same, if you are using the 28-200

on a film SLR and the 18-55 on the 300D, the only camera it will fit on.

Of course if you put the 28-200 on the 300D it becomes a 45-320...
