What sets the Ef 75-300mm f/4-5.6 Iii Lens apart is its compact and lightweight design, making it a perfect companion for capturing high-quality sports, portrait, and wildlife photography. This 4x telephoto zoom lens boasts a silver ring on the front part of the zoom ring, adding a touch of luxury to its aesthetic appeal. The lens shares the same optical system, construction, and exterior as the Ef 75-300mm f/4-5.6 Iii Usm, but with a key difference - it utilizes a Dc motor instead of a Usm to drive the autofocus (AF). This feature ensures fast and accurate AF, making it an excellent choice for sports and other fast-paced photography scenarios. The Ef 75-300mm f/4-5.6 Iii Lens maintains the compact size, close focusing range, and accessory compatibility of the Usm lens, making it a versatile and practical addition to any photographer's gear.
