Widely regarded as one of – if not the – best general purpose lenses available (from any manufacturer, not just Canon), the 24-70 is the gold standard of a walking-around medium range zoom lens. From wide-enough 24 to tele-enough-70, this lens can get you through a day, a week, a month or even a year (do I have a song stuck in my head? Shoot me). Crazy sharp with excellent detail and beautiful contrast, saturation and hue – the 24-70 earns its reputation, often being the only lens even the most kitted-out photographers use on shoot.
But don’t take our word for it – listen to what Guest Photographer BJ Formeto of F+F has to say about the Canon EF 24-70 f/2.8 L USM Lens:
From Canon USA (refers to the Mark II version of the lens):
Meeting the ever-increasing demands on image quality that digital photography brings, the redesigned EF 24-70mm f/2.8L II USM is the latest update to the acclaimed L-Series of EF optics, re-establishing a new standard for superb optics, high-end durable construction and performance in professional zoom lenses. A standard focal length zoom lens, it features a large aperture throughout its focal length. Featuring the latest advances in optical lens design, it utilizes 1 Super UD lens element and 2 UD lens elements that help minimize chromatic aberration in the periphery at wide-angle as well as reduced color blurring around the edges of the subject. In addition, 2 types of aspherical lenses are combined to help reduce spherical aberration over the entire image area as well as through the full zoom range. Optimized lens coatings also help ensure exceptional color balance while minimizing ghosting. The lens is also equipped with a circular 9-blade diaphragm for beautiful, soft backgrounds. A ring-type USM and high-speed CPU with optimized AF algorithms enable silent and fast autofocusing. Built for the rigors of professional use as well as to meet the increased number of shots available with digital photography, it’s constructed with improved dust sealing and water resistance while fluorine coatings on the front and rear lens surfaces help reduce soiling, smears and fingerprints. A zoom lock lever locks the zoom position at the wide end for safe transporting while attached to an EOS DSLR camera over the shoulder.
