The EF 100mm f/2.8L IS USM Macro is a professional-grade lens designed for Canon EOS DSLR cameras. It is primarily used for close-up photography and is especially popular for shooting insects, flowers, and other small subjects.

The lens has a maximum aperture of f/2.8, which means it can produce sharp images even in low light conditions. It also has a 9-blade circular aperture that can create beautiful bokeh (out-of-focus areas in the background).

One of the key features of this lens is its Hybrid Image Stabilization system, which can compensate for camera shake up to four stops. This is especially useful when shooting at close distances, where even the slightest camera movement can cause blur.

The lens also features an Ultrasonic Motor (USM) for fast and quiet autofocus, as well as full-time manual focus override. It has a minimum focusing distance of 0.3 meters, and a maximum magnification ratio of 1:1, which means the subject will appear life-size on the camera's sensor.

The lens is also built to withstand tough shooting conditions, with dust and moisture-resistant construction and a durable metal lens mount.

Overall, the EF 100mm f/2.8L IS USM Macro is a versatile and high-quality lens that is ideal for macro photography, portrait work, and other applications where a fast, sharp lens is essential.
