I think USM is the ultrasonic motor and it operates better to EF
: During this I came across two different camera kits.
: 1. Canon Rebel 2000 body with EF 28-80mm lense
: My doubt is what is the difference between terms EF and USM? And which one is better for beginners like me.
: Can anyone guide me which one is better?
