Canon EF 75-300mm f/4-5.6 III USM Lens
The Canon EF 75-300mm f/4-5.6 III USM is a highly portable and lightweight 4x telephoto zoom lens, ideal for photographers looking to bring distant subjects into clear focus. Covering a versatile range from portrait-length to deep telephoto, this lens is well-suited for sports, wildlife, and outdoor portraiture. This specific “USM” version features an upgraded autofocus motor, providing the speed and silence required for capturing fast-moving action and candid moments.

Reach and Performance
Versatile Telephoto Range: Designed for full-frame Canon EF-mount DSLRs, this lens is also a powerful option for APS-C sensor cameras, where it provides a massive 120-480mm equivalent focal length range.

Micro Ultrasonic Motor (USM): The integrated micro USM delivers noticeably faster, quieter, and more precise autofocus compared to standard DC motors. This makes it an excellent choice for both high-speed stills and video applications.

Electromagnetic Diaphragm: Works in perfect sync with the USM to ensure consistent exposure and aperture control, even when shooting at your camera’s fastest continuous burst speeds.

Optical Quality and Bokeh
Super Spectra Coating: Individual lens elements are treated with Canon’s specialized coating to suppress lens flare and ghosting. This technology ensures your images maintain high contrast and accurate, neutral colors even when shooting in bright or backlit conditions.

Smooth Background Blur: A seven-blade diaphragm produces a smooth and pleasing quality in the out-of-focus areas (bokeh), allowing you to isolate your subject effectively against a soft background.

Compact Design: Despite its significant reach, the lens maintains a relatively slim and lightweight form factor, making it a comfortable addition to your camera bag for travel or long days in the field.
