EF 75-300mm f/4-5.6 IS USM

The Canon EF 75-300mm f/4-5.6 IS USM is a telephoto zoom lens designed for Canon EOS digital and film cameras that features a built-in image stabilization system to reduce blurriness caused by camera shake. The lens incorporates gyro sensors and a microcomputer-controlled mechanism that shifts internal lens elements to compensate for unintended camera movement, enabling sharp photographs at longer focal lengths with slower shutter speeds. The image stabilization system effectively reduces the required shutter speed by two full stops, allowing photographers to capture sharp images at 200mm focal length using a shutter speed of 1/60th second.

This lens combines Canon's USM (ultrasonic motor) autofocus technology with the variable aperture of f/4-5.6 across its zoom range, making it suitable for wildlife, sports, and telephoto photography applications. The combination of its focal range, stabilization features, and autofocus capability makes it a versatile addition to Canon EOS camera systems.
