Canon EF 17-35mm f/2.8L USM

The Canon EF 17-35mm f/2.8L USM is a premium ultra-wide zoom lens designed for professionals requiring consistent performance across its range. Part of Canon's prestigious L-series, it features weather-sealing and superior build quality with constant f/2.8 aperture throughout the zoom range. Its Ultrasonic Motor delivers swift, silent focusing while high-quality optics with UD glass elements minimize distortion and chromatic aberration. Though superseded by newer designs, this durable lens remains valued for architectural, landscape, and photojournalistic work where its wide field of view and excellent edge-to-edge sharpness prove indispensable on both full-frame and crop-sensor bodies.
