Canon's EF 24-70mm f/2.8L II USM Lens is an advanced zoom lens designed for superb performance and high-end durability. It offers both 35mm Film or Canon APS-C format compatibility. Canon has packed this lens with tons of professional grade features including one Super UD lens element and two UD lens elements in its optical design that work to drastically reduce chromatic aberrations at the edges of the wide-angle perspective. 

Canon L Series

The L Series denotes Canon's professional line of lenses. Though used extensively by non-professionals, these lens have been engineered to the highest of standards. These luxury lenses incorporate such advanced optical advantages as Super Low Dispersion Glass, Ultra-Low Dispersion Glass, flourite elements and aspherical design elements. All of these combine to produce reliably incredible images.

Fluorine Coating

Canon L Series lenses feature a fluorine coating on the front and rear surfaces. This coating helps to greatly reduce smears, smudges or fingerprints ensuring that you will always take impeccable images.

Ultra Sonic Motor (USM)  

Canon's USM lenses employ a motor powered by ultrasonic waves that produce a quiet, yet high-speed AutoFocus. You can enjoy high performance with low noise in a variety of shooting situations.

Anti-Reflective Coating 

The Canon anti-reflective coating is an optical design feature which ensures superior clarity and image brilliance, even in poor or unfavorable lighting conditions. Canon applies the anti-reflective coating through a special process, layering the lens surface in order to substantially reduce unwanted flare or ghosting. This process helps to ensure incredibly rich image contrast and true color fidelity. 

Aspherical Design 

Canon's aspherical lens design creates a more complex surface profile. This helps to greatly reduce spherical and other optical aberrations. The design further ensures consistent imaging performance throughout the entire focal range, while delivering incredible sharpness up to the periphery of the image. 

Manual Focus 

Manual focusing means you have all the control at the end of your fingers. Canon lenses feature a specially designed ergonomic construction that is noticeable at first touch. The large rotation angle of this lens guarantees precise focusing. The mechanism moves super smoothly and without extra play, furthering the intuitive interaction along the focal plane.  

Advanced Aperture Design

The circular aperture produces a natural background blur. With Canon lenses you can create stunning Bokeh effects, thanks to the finely tuned features and advanced optical design. By keeping the background intentionally blurred, additional focus is created on the subject of an image. The uniquely engineered diaphragm blades of this lens, along with the virtually circular aperture, deliver stunning renditions of highlights the back and foreground.

Ultra Low Dispersion Glass (UD)

Canon's Low Dispersion technology is engineered to reduce chromatic aberrations, eliminating the tendency of light of different colors to focus to different points at the image plane. This means your images will come out crisp and clear, with less of a chance of defracting light into an unwanted rainbow of colors. Take shots exactly like you want, without any flare-up or blurring.
