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.
