To meet the growing demand of digital SLR owners, this ultra-wide-angle zoom offers a broader view, fast aperture, and closer focusing

Developed to succeed the high-performance 17-35mm f/2.8L USM, the EF 16-35mmf/2.8L USM has the leading wide-angle range in its class. Due to the proliferation of digital SLR Camera’s that tend to have a smaller frame size when compared to the 35mm,there is a demand for shorter focal length lenses, and this has resulted in the development of the EF 16-35mmf/2.8L USM. This is the first EF lens to have three types of aspherical elements (ground, replicated and Gmo [glass molded] which effectively correct the lens aberrations which occur during zooming. And despite its longer zoom range the EF16-35mm f/2.8L USM obtains a higher image quality than any other lens in its class.

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′).
