The Canon EF 16-35mm f/4L IS USM is a professional wide-angle zoom lens that combines advanced optics, image stabilization, and rugged build quality in a compact package. Covering a versatile focal length range ideal for landscapes, architecture, interiors, and travel, it maintains a constant f/4 maximum aperture for consistent brightness throughout the zoom range. Its sophisticated optical design integrates two ultra-low dispersion glass elements to minimize chromatic aberrations and three aspherical elements to control distortion and spherical aberrations, resulting in sharp, high-contrast imagery across the frame. To further enhance performance in strong lighting, a Super Spectra coating reduces flare and ghosting for faithful color reproduction and improved clarity. A four-stop-effective Optical Image Stabilizer minimizes camera shake, making handheld shooting in low light possible without compromising sharpness. Autofocus performance is fast, accurate, and quiet thanks to a ring-type Ultrasonic Motor and internal focusing mechanism, with full-time manual focus available for precision adjustments. A rounded nine-blade diaphragm contributes to pleasing out-of-focus highlights, enhancing selective focus techniques. Designed for demanding use, this L-series lens is weather-sealed to resist dust and moisture and includes fluorine coatings on the front and rear elements to reduce smudging and ease cleaning. Combining portability, sharpness, and durability, the EF 16-35mm f/4L IS USM is an excellent choice for professionals and enthusiasts seeking reliable wide-angle performance.Manufacturer Items Include:Canon EF 16-35mm f/4L IS USM LensCanon E-77 II Lens CapCanon Lens Dust Cap E (Rear)Canon EW-82 Lens HoodCanon LP1219 Soft Lens CaseBundle Items Include:Canon EF 16-35mm f/4L IS USM LensCanon Mount Adapter EF-EOS RShoulder Bag64GB Memory Card
