Key Features — Canon 70-300mm f/4.5-5.6 DO IS USM
Diffractive Optics Element: Canon's DO multilayer diffractive optical element reduces the lens's physical length compared to conventional telephoto zooms of the same range.
70-300mm Telephoto Zoom: Covers a versatile focal range suited to wildlife, sports, and portrait photography from a comfortable shooting distance.
f/4.5-5.6 Maximum Aperture: Variable maximum aperture provides reasonable light-gathering ability across the full zoom range.
Optical Image Stabilization: Built-in IS helps counteract camera shake for sharper handheld results, particularly at longer focal lengths.
Ring-Type USM Autofocus: Ultrasonic motor delivers fast, quiet autofocus with full-time manual focus override without switching modes.
