The EF28-70mm f/3.5-4.5 II is a standard zoom lens that has a 2.5x zoom ratio spanning from a wide-angle focal length of 28mm to a medium telephoto of 70mm, and a macro mechanism enabling shooting from a close distance of as little as 39m at all focal lengths.
By adopting an aspherical optical lens and a unique three-group zoom optical system, the lens can be used like a standard zoom lens by anyone due to its compact size and excellent operability such as the overall length not changing even when zooming.
