Hi Ken, Are you still talking to me? 3:-)

This is one reason why Canon has introduced some lenses unmatched by the others. With the EF mount, both the aperture and the AF controls are transferred via flexible wires, so you can place the zoom ring, focusing ring and aperture mechanism anywhere you want within the lens, and you don't have to worry about how you would manage the mechanical coupling with the body (like Pentax and Nikon must do). Plus an electronic aperture control is inherently faster, more precise, and less failure-prone than a mechanical one. > Hope this is the direction they are going to, and the rumoured new > series of lenses planned for the fall announcement would be just > that :-). For this I am less than optimistic... I do not believe in such a move anyway, but we are now seeing a new lens and camera series, new body chasis, and you would think, won't you, that if such a radical change were coming, they would make the switch all at once?
