The Canon 100mm f/2.8L IS Macro is a major improvement over the excellent Canon 100mm f/2.8 Macro it replaces. Key features include:

• Four-stop image stabilization

• Weather sealed

• Improved motor

• Improved aperture ring

Improved Image Stabilization. The Canon 100mm f/2.8L IS Macro boasts L-series designation, weather sealing, and Canon’s four-stop hybrid image-stabilization system. The hybrid image-stabilization system compensates for linear and rotational shake, making image stabilization more effective at close distances.

Advanced Optics and Focusing. With fifteen elements in twelve groups, an improved ultrasonic motor, and a nine-blade aperture ring for smooth out-of-focus highlights, the f/2.8L IS Macro represents a major improvement over the already-excellent lens it replaces.
