Ranging from portrait-length to medium telephoto, the EF 70-300mm f/4-5.6 IS USM from Canon is a versatile tele zoom characterized by its relatively lightweight and compact design. Its optical layout utilizes one ultra-low dispersion element to control color fringing and chromatic aberrations for improved clarity and a Super Spectra coating has been applied to suppress flare and ghosting for greater contrast. Complementing the imaging performance, this 70-300mm also features a three-stop-effective Image Stabilizer system that minimizes the appearance of camera shake for sharper handheld shooting. Additionally, a micro USM also affords quick, quiet, and accurate autofocus performance to suit both photo and video applications.
