Canon 75-300mm Lenses Reviewed | Cameras Direct Australia
There is currently (2105) two versions of the Canon 75-300mm lens. The choices are with or without "USM". What is USM? It is the "ultrasonic motor' which is the focusing motor. The USM version will focus faster and quieter than the non -USM lens.
Is the USM lens worth roughly $75 more? Well depends on you really. Lets put it this way, if budget is critical, the non-usm lens that you own, will take a better photo than than the USM lens that didn't buy!
The following video review of Canon's 75-300mm USM Zoom lens will explain a little more for you. Thanks for considering Cameras Direct. We hope to hear from you soon.
