(Open Box) Canon EF 70-300mm f/4-5.6 IS USM - EF-mount Camera Lens

The Canon EF 70-300mm f/4-5.6 IS USM was developed as a premium alternative to the budget 75-300mm series, inheriting many optical technologies typically reserved for Canon’s professional L-series. It is a versatile "workhorse" lens that provides a massive 4.3x zoom range. On APS-C sensor cameras (like the Rebel or 90D series), it offers a staggering 112-480mm equivalent field of view, making it a favorite for amateur birders and sports photographers who need maximum reach without the weight of a professional prime.

Advanced Stabilization and OpticsThree-Stop Image Stabilizer (IS): The built-in stabilization compensates for camera shake, allowing you to shoot handheld at shutter speeds up to eight times slower than usual. It features two modes: Mode 1 for static subjects and Mode 2 for horizontal panning with moving action.Ultra-Low Dispersion (UD) Element: Unlike standard consumer zooms, this lens incorporates a UD glass element to significantly reduce chromatic aberrations (color fringing), resulting in higher contrast and sharper subject outlines.Super Spectra Coating: Specialized lens coatings minimize flare and ghosting—essential when shooting toward bright light sources in stadiums or open fields.

Fast and Quiet Operation

Micro-USM (Ultrasonic Motor): Delivers rapid and quiet autofocus, ensuring you can track fast-moving subjects without loud mechanical noise.

Zoom Lock Mechanism: A dedicated lock switch at the 70mm position prevents "lens creep," keeping the lens barrel securely retracted while you’re hiking or traveling with the camera over your shoulder.

Circular Aperture: The 8-blade circular diaphragm creates a more natural, rounded blur in the out-of-focus areas, helping your subjects stand out against a creamy background.
