What is the difference, pros and cons of a zoom lens that uses a DC motor instead of a USM to drive the AF?
I'm looking for buy a zoom lens for my Canon Rebel XT. I can not afford one with the IS. so my two options are the 75-300 mm, but have 2 different types. So I want to help in the choice of what would be the best option.
Ultrasonic Motor (USM) will be quieter and use less battery power. G-day!
