- I don't understand why it is right to put moters in the lenses.
- If you have 10 lenses, it is more economical to have one motor in
- the camera body than to have 10 motors, one in each lense.
- I suppose that the advantage to put the motor in a lense is
- that this way the motor produces more torque to move
- the glass. If so, only BIG lenses need motors in them, such as
- the 600mm/f4. For wide angle to short telephoto lenses, the F4,
- N90 or even the 8008s do not focuse perceivably (at lease to me)
- more slowly than the Canon's. However, the extra motor in the
- Canon lenses (wide angles to short telephotos) is going to cost
- more for the buyers.
