Canon EF 100mm f/2.8 Macro USM Lens

Canon EF 100mm f/2.8 Macro USM Lens
The Canon EF 100mm f/2.8 Macro USM is a legendary prime lens that excels in both high-magnification macro photography and professional portraiture. Offering a “life-size” 1:1 magnification, this lens allows you to capture the smallest details of the natural world with incredible precision. Its combination of a flattering short-telephoto focal length, rapid autofocus, and superb edge-to-edge sharpness makes it a versatile staple for any Canon photographer’s kit.

Precision Macro & Portrait Capabilities
True 1:1 Magnification: Capture subjects at life-size on the camera sensor, making it the perfect tool for insects, flowers, jewelry, and fine textures.

100mm Short Telephoto Focal Length: Provides a comfortable working distance for macro shots and a highly flattering perspective for portraits, featuring beautiful compression and subject isolation.

Three-Group Floating System: This advanced internal focusing design ensures that image quality remains consistently sharp and high-contrast from the minimum focusing distance of 1 foot all the way to infinity.

Advanced Optical Engineering
Ultra-Low Dispersion (UD) Element: Significantly reduces chromatic aberrations and color fringing, resulting in images with high clarity and accurate color rendering.

Super Spectra Coating: Applied to lens elements to effectively suppress flare and ghosting, ensuring neutral color balance and high contrast even in backlit or bright-light scenarios.

8-Blade Rounded Diaphragm: Produces a soft, circular bokeh that beautifully renders out-of-focus highlights, which is essential for creative selective-focus techniques.

Fast & Intuitive Handling
Ring-Type Ultrasonic Motor (USM): Provides lightning-fast, near-silent autofocus. Because the motor is ring-type, it also allows for full-time manual focus override, so you can fine-tune your focus point without leaving AF mode.

Focus Limiter Switch: To speed up performance, you can constrain the autofocus range to specific distances (1’–infinity or 1.6’–infinity), preventing the lens from “hunting” through its entire range during non-macro use.

Internal Focusing: The lens does not change length during focusing, which is critical when working very close to skittish subjects like insects.
