The Canon EF 24-70mm f2.8L II USM telephoto Lens has been announced by Canon and by the looks of the specification below and from the initial reviews it looks like a superb lens building on the pedigree of its predecessor and totally re-designing its optics to enhance image quality.
Canon EF 24-70mm f2.8L II USM Lens Construction
This second revision the Canon EF 24-70mm f2.8L II USM Lens has 18 elements in 13 groups, with the inclusion of two Ultra-low Dispersion (UD) and one Super US aspheric elements which Canon says minimises colour blurring and chromatic aberration, in addition the lens features a fluorine coating which should help to reduce dust and finger print build-up which also produce a superior crystal clear image.
Minimum focusing distance on the updated version remains the same as its predecessor and the angle of view remains the same however this lens features a larger filter size with an increase from 77mm to 82mm
Weight and size wise the Canon EF 24-70mm f2.8L II USM Lens measures 88.5 X 113 mm (3.5 x 4.4”) with these measurements this lens has a wider diameter while at the same time being shorter than its predecessor (Mk I Lens measurements 83 x 123 mm) as far a weight goes the new lens is significantly lighter at only 805g (28.3oz) predecessor 950g.
The ring type USM drive and autofocus allows autofocusing to be overridden at any time by the photographer giving total control for minor focus adjustments.

Canon have the following to say about the Canon EF 24-70mm f2.8L II USM:
“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.”
Canon say the Canon EF 24-70mm f2.8L II USM will be available from April 2012 and will retail for US $2,299.00
