The official marketing text of Canon EF24-70mm f/2.8L USM Zoom Lens as supplied by the manufacturer
The EF 24-70mm f/2.8L USM is a high-performance lens. It has been developed as a successor to the EF 28-70mm f/2.8L USM, but with a wider zoom range to meet the needs of photographers using certain digital cameras.


-High-speed AF.
-Optimized lens coatings.
-Highly resistant to dust and water droplets.
-Min. focusing distance of 0.38m at all focal lengths.
-Front of lens does not rotate during focusing.
-Manual focus is possible in AF mode.
-Only lead-free glass is used.

The EF 28-70mm f/2.8L USM has proven very popular with professional and advanced amateur photographers since it was introduced in 1995. However, the increasing use of digital cameras, most having sensors smaller than a 35mm film frame, has increased the demand for a high-performance standard zoom lens with a wider wide-angle setting. The EF 24-70mm f/2.8L USM lens meets this need. The optical design is based on the previous lens, but incorporates new design features that allow the broader focal length range while maintaining the superb image quality. At the same time, the minimum focusing distance has been reduced from 0.5 metres to 0.38 metres.
Improved water and dust resistance ensure that it will become the leading standard zoom lens in the EOS system.

Lens system
Lens structure (elements/groups)*
The way in which a camera lens is constructed.
Focal length range (f-f)
Measure of how strongly the system converges or diverges light. For an optical system in air, it is the distance over which initially collimated rays are brought to a focus. A system with a shorter focal length has greater optical power than one with a long focal length; that is, it bends the rays more strongly, bringing them to a focus in a shorter distance.For an optical system in air, the effective focal length (f and f′) gives the distance from the front and rear principal planes (H and H′) to the corresponding focal points (F and F′).
