id prefer it the other way arround.
i have and always will have a low budged and lets face it canons budged lenses arent as food as nikkons budged lenses specialy when it comes to focussing.
canon would do good to get rid of these crappy micromotor lenses all toherget and ask 10 euro more for usm in evert single lense.
they had usb in old lenses like the 24-80 wich was quite fast (bad quality tho) so why not in the new ones?
it obviously doesnt cost a lot to implement so stop being cheap canon and use usm in every lens even kit lenses.
