Hand-held low light shooting
The EF 24-70mm f/2.8L II USM’s constant f/2.8 aperture throughout the zoom range makes the lens a great low light performer that’s able to make the most of any available ambient light. The fixed aperture also gives you optimum control over depth-of-field. The new 9-bladed diaphragm produces a circular aperture, which helps to achieve beautifully blurred backgrounds with attractive bokeh. This means your subject can stand out against the background, with no distractions.
 
Next generation optical design
Featuring the latest advances in optical design, the EF 24-70mm f/2.8L II USM brings together three aspherical elements to provide the highest possible image quality in a lens of this focal length. Significant reduction in chromatic aberration and reduced colour blur means less time in post production with an edge-to-edge sharpness usually only found in prime lenses.
